I solved it by uninstalling and installing again.

Have you defined Document in your process? (Select Pool → Data → Documents).
In this definition you should choose to initiate this document from contract and select appropriate field from contract (with type “File”).

i have done exactly what you said BUT i don’t want to show it at the instantiation form.
At UI designer - > formInput(json) i defined them null but still can’t submit the form.
This is what i get : { “exception”: “class org.bonitasoft.engine.exception.BonitaRuntimeException”, “message”: “USERNAME=jan.fisher | org.bonitasoft.engine.persistence.SRetryableException: javax.persistence.PersistenceException: org.hibernate.exception.ConstraintViolationException: could not execute statement” }

Sorry, but I’m not able to help you without source codes. I have exactly the same case in my process, but it works perfectly for me (version 7.3.1). Even when I tried I wasn’t able to recreate the exception that you got.
