Rest API issue with TextArea

[deepyamanchatte]

Hi

I am new to Activiti and using the version 5.17.

I have successfully drawn a process diagram with custom fields i.e. textarea and deployed the same on activiti-explorer2. My process works fine on the explorer with the custom field.
I am having a problem when I am trying to start a new process instance for the same using the REST API.

eg.
http://localhost:8080/activiti-rest/service/repository/process-definitions/CatalogueApproval:2:25004

Error: {"message":"Bad request","exception":"unknown type 'textarea' initcomments"}

Request for some insights on the problem.

Regards

Deepyaman

The process engine in the REST application also needs to know the custom form fields (this is what the exception is hinting at)
