Hello, I made an upgrade of Nifi from 1.9.2 to 1.11.3 and I see a problem when Terminate a Groovy ExecuteScript process.
The steps to replicate are : GenerateFlowFile -> Groovy ExecuteScript -> LogAttribute The executeScript code: def flowFile = session.get() sleep(20) session.transfer(flowFile, REL_SUCCESS) When ExecuteScript are running , Stop and Terminate the processor, The processor become invalid with the message: 'Script engine' validated against 'groovy' is invalid because Given value not found in allowed set 'ECMA Script' After that its not possible to set 'script Engine' property to Groovy and the only workaround i found is to clone the executeScript and replace the invalid one with the cloned.
