currently I'm facing a strange situation with the execution of a workflow. When I execute it it works fine and it completes the entire process. But when I reset it and I relaunch it I got a strange error during the execution on console log for two Database Pivot nodes that I use, here below the error:
Configure failed (StringIndexOutOfBoundsException): String index out of range: -2
These database pivot nodes are within 2 loops, of course I dont' know if this is the main cause of this error. Anyway the workflow execution is not blocked by this error. So, I got the final result and the workflow execution is correctly completed. But during the process the error comes out and I got some minutes the classic red cross.
Someone can explain me how can I fix it, or maybe give me any smart suggestions?
Thanks in advice.
