Description
- given:
- I start a process instance with a file variable
- The process instance is pending in a wait state
- I remove the file variable
- when:
- I retrieve the historic details via REST-API or variable updates via optimize REST-API endpoint
- then:
- I get an error message as a response with status code 500
- expected:
- I can retrieve variable updates even if a file variable was removed
Hint:
- This is the error message you get:
