and when I submit a document ,the similar errors will come “Copy failed: No source data available: … …”,the process I defined can’t get the data from the document I have sent.
“Copy failed” is not necessarily an “error message”. It just means that a Flow Map Copy command did not copy any data. Many documents have fields that are optional. Before the Flow Map Copy command was executed there was no field in the pipeline at the “from” path.
If you believe this message is displayed when there really is from-data, add a pub.flow:tracePipeline to the Flow to verify.
I added a pub.flow:tracePipeline into the flow ,then I find my CPU usage in task manager is 100%, and my pc become very slowly ,it seems my pc have been blocked . Could you tell me how to solve it?
