Flow throws error without obvious reasonIssue There is an issue with a custom Flow to update the Service task requested for with the value of a reference field in the variables section of the service task It was working fine for a while, but then without any changes, it has started to throw errors - 'invalid return type: com.glide.vars2.Variable' ReleaseOrlandoCauseFlow has to be in global application. Then only we are able to access the variables in service task. After creating another flow we are able to see the flow went successfully.It is not possible to use the Reference fields in the inline scripts of the flow designer and we have tested in OOB (out of box) and it is not able to the copy the value of a reference field from the variables section. This is expected behavior.Resolution After creating another flow in global, we are able to see the flow went successfully and we are able to access the variables of service task through inline scripts.
