HI 
I have an issue message in Camunda when I try to deploy simple UI
I uploaded the same example in Camunda Doc and also I write the key (embedded:app:forms/approve-loan.html) in the Modeler. The error is (the context path either empty)
Hey @jessca,
how did you deploy the Process? The :app: in the key implies that it is part of a process application.
yes i use key in the form (embedded:app:forms/approve-loan.htm)
You either have to deploy it as a process application, use the REST-API to deploy your process together with the form or provide the form at a static URL so it can be referenced. Depending on that, the form URL changes.
Check here on how to reference it
