The process or template contains a form field (in either a task form or a launch form) whose field type is text, textarea or hidden.
The value submitted for this field must be a string. The length of the string is greater than the maxLength that the process or template author set for the field.
Possible Causes and Suggested Actions
The value of one of the field exceeds the maximum permitted value. Reduce the length of the value.
The value needs to be replaced with a valid value.
