Script Task element
After adding the Script Task element, consider adding either of the following Boundary-type Process model elements to design business solutions when your best-case scenarios don't happen:
After the element is placed into the Process model, you may adjust its location in the following ways:
Moving a Script Task element has the following limitations in regards to the following Process model elements:
    Pool element: If the Script Task element is inside of a Pool element, it cannot be moved outside of the Pool element. If you attempt to do so, Process Modeler places the Script Task element inside the Pool element closest to where you attempt to move it.
    Lane element: If the Script Task element is inside of a Lane element, it can be moved to another Lane element in the same Pool element. However, the Script Task element cannot be moved outside of the Pool element.

Customize the Appearance of a Script Task Element

Customize the Script Task Element's appearance in the following ways:
After a Script Task element is added to a Process model, optionally customize these aspects of its appearance. Each Script Task element's appearance may only be changed individually.

Configuration Panel Settings

Edit the Element Name

An element name is a human-readable reference for a process element. Process Modeler automatically assigns the name of a Process element with its element type. However, an element's name can be changed.
Follow these steps to edit the name for a Script Task element:
    1.
    Select the Script Task element from the Process model in which to edit its name. Panels to configure this element display.
    2.
    Expand the Configuration panel if it is not presently expanded. The Name setting displays. This is a required setting.
    3.
    In the Name setting, edit the selected element's name and then press Enter.

Select the ProcessMaker Script to Run

Since Script Task elements are designed to run a Script, specify which Script a selected Script Task element uses. A Script must already exist before it can be selected for use in a Script Task element.
See the following topics for more information:
Ensure to select a Script for each Script Task element in your Process model. If a Script is not specified and Requests are started for that Process, Requests associated with that Process will stall and never complete because there is no Script to run for the Script Task element(s).
Follow these steps to select a Script for a Script Task element:
    1.
    Select the Script Task element from the Process model in which to specify its Script. Panels to configure this element display.
    2.
    Expand the Configuration panel if it is not presently expanded, and then locate the Script setting.
    3.
    From the Script drop-down menu, select which Script that Script Task element references. After a Script is selected, the Open Script link displays.
    4.
    Optionally, click the Open Script link to view and/or edit your selected Script. Note that your user account must have appropriate Script category permissions to view and/or edit the selected Script.
If no Scripts exist, the Script drop-down menu contains no options. Ensure to select and configure a Script for every Script Task element in the Process model before deploying your Process.

Configure the Selected ProcessMaker Script

After selecting the Script for the Script Task element, optionally provide a JSON object that configures variable values for the selected Script. Providing a JSON script from the Script Task is identical to providing JSON configuration script in the Script Config JSON panel in Scripts Editor for a Script.
See the following topics for more information:
If a JSON script exists in the Script Task element, that script is used for the Script. An existing JSON configuration script displays in the Script Configuration option for a selected Script Task element.
The JSON script in the Script Task element overrides any JSON script entered in the Script Config JSON panel in Scripts Editor for the associated Script.
Follow these steps to enter or edit a JSON configuration script for a Script Task element:
    1.
    Select the Script Task element from the Process model in which to specify its Script. Panels to configure this element display.
    2.
    Expand the Configuration panel if it is not presently expanded, and then locate the Script Configuration option.
    4.
    Click the icon
    beside the Script Configuration option. The Script Config Editor displays.
    5.
    Enter your JSON configuration script. Use the scroll panel to the right of the Script to scroll to different sections of the Script if necessary. This is useful especially when you are editing a long Script.
    6.
    Click Close or the Close icon
    .
You can enter your JSON configuration script directly into the Script Configuration option instead of using the Script Config Editor.

Vocabularies Panel Settings

Assign ProcessMaker Vocabularies That Validate Request Data from This Element

Assign Vocabularies that validate that Request data complies with a specific JSON schema. This is often mandatory for many types of business sectors including banking and healthcare. Ensure the quality and compliance of Request data. For example, during a Loan Application process, ensure that personal information has been included in the Request to that moment in that in-progress Request. The Vocabularies package must be installed to make this configuration.
Use a Vocabulary on a Script Task element to validate that Request data complies with the Vocabulary's JSON schema after the Script Task runs its Script but prior to when the Request continues workflow. See What is a Vocabulary? for more information.
Each moment ProcessMaker evaluates workflow routing for an in-progress Request, ProcessMaker also evaluates the Request data's conformity to the Vocabularies applied to the Process and/or a specific BPMN 2.0 element in the Process model. The Request's JSON data model must conform to the Vocabulary's JSON schema.
During an in-progress Request, if ProcessMaker evaluates that the Request data no longer complies with all Vocabularies to that moment, the Request status changes from In Progress to Error. The error displays in the Request summary. Vocabularies are cumulative in an in-progress Request: as the Request progresses, if Request data does not conform with any Vocabulary's JSON schema to that moment in the Request, the Request errors.
If no Vocabularies are assigned, ProcessMaker does not validate that Request data complies with a specific JSON schema prior to continuing workflow for that Request.
One or more Vocabularies must be created before assigning a Vocabulary. See Create a New Vocabulary. Multiple Vocabularies can be assigned to a Script Task element.

ProcessMaker Package Required

The Vocabularies package must be installed to assign which Vocabularies validate Request data at a Script Task element. Use the Vocabularies package to maintain uniform JSON schemas across all assets in your organization. These assets include Processes, Screens, and Scripts.
A Vocabulary is a JSON schema. The JSON schema describes the data objects, types, and structure that you want in both a machine and human readable format. Apply one or more Vocabularies to your Processes and/or specific BPMN 2.0 elements in your Process models to ensure the JSON data model in Request data complies with the data structure outlined in the JSON schema that you need to meet regulatory specifications or ensure Request data contains required information.
Follow these steps to assign Vocabularies that validate Request data from a Script Task element:
    1.
    Select the Script Task element from the Process model in which to assign Vocabularies that validate Request data prior to when this element completes. Panels to configure this element display.
    2.
    Expand the Vocabularies panel if it is not presently expanded. The Assigned setting displays.
    3.
    Click the
    icon to add a Vocabulary. The Assign Vocabulary setting displays.
    4.
    From the Select Vocabulary drop-down menu, select a Vocabulary from which to validate Request data complies with its JSON schema.
    If no Vocabularies are configured, then the following message displays: List is empty. Create at least one Vocabulary. See Create a New Vocabulary.
    5.
    Click Save.
    6.
    Repeat Steps 3 through 6 as necessary for each Vocabulary required to validate Request data complies with its JSON schema.
Click the Remove icon
from the Vocabularies setting to remove a Vocabulary from assignment to this element.
After one or more Vocabularies are assigned to a Script Task element, the Vocabulary icon displays in that element.
