Ensure the maximum length of each property is not
0 or a negative number: Except for the root of the JSON schema, such as
mainSchema, each property in a JSON schema and Vocabulary must have a length that validates how many digits, whether alphabetical, numeric, or alphanumeric, that validates conformity of data for that property. ProcessMaker stores a property's length using the
maxLength key name by default to define the maximum number of digits that property's value may contain. For example, a person's age may contain no more than three (3) digits. Ensure that each property contains at least one (1) digit. To specify a minimum digit length of a property, select the Code tab and enter that minimum length using the
minLength key name. To specify an exact number of digits, use
minLength key name. For example, a credit card number must contain 16 digits.
