Steps to reproduce

1. Deploy a BPMN model with a User Task and the following form field constraints:

   <camunda:formField id="StringField" label="A string field" type="string">
     <camunda:validation>
       <camunda:constraint name="maxlength" config="20" />
     </camunda:validation>
   </camunda:formField>
   

1. In Tasklist, start a new process instance
2. Enter a string with 20 characters
3. Complete the task

Observed Behavior

• The frontend validation passes
• The backend validation fails

Expected Behavior

The backend validation for maxlength is inclusive (similarity to minlength) and therefore accepts a string with 20 characters.
