InboundNamedPipe::ReadFile: Not enough bytes read. NOT USING UNION TOOL

MinaGO

I am aware there is a post already on this problem, however, my workflow contains no union tool as is discussed in the other post and still I get this problem. I have no idea how to get my workflow to run.Screenshot (100).png

Hi @MinaGO

 

This error can also be because of a corrupted yxdb file. Can you troubleshoot this by reading in the yxdb in a seperate module?

 

If this runs you can then look to test the output tool in the same fashion.

 

Users have had success by recreating the workflow within another module as well.

Sorry, I am a bit of a noob still especially when it comes to certain terminology. When you say 'reading the yxdb in a seperate module' do you mean can I open the file in a different workflow? If so then yes I was able to browse/output the file. If not can you elaborate please.

Hi @MinaGO

 

Apologies. You interpreted that corrrectly. Can you continue to add the generalize tool and the output tool in that module and see if it still gives you the same error.

Still got the same error when recreating it, even when we recreating the input file. But I think I realised why, the generalise was being used on a file that had already been processed by the tableau polygon macro so I think that may have been why it was giving an error (although the error doesn't really indicate this at all). You think so too?

Hi @MinaGO

 

This could well have been the reason as usually the error indicates something has been corrupted. 

 

The error can sometimes also be memory related, but if you have the original file you should be able to test this out.

Finding that it happens again before using a tableau polygon as well. Not sure if its that im trying to generalise a generalised polygon.

Hi, I have this problem occurring in my workflows and for me, it has something to do with the Message and Download tools.

 

Attached are two workflows which reliably recreate the problem for me. Run the Test-Pipe-Error.yxmd workflow - on my system, on average, every 3rd run yields the error.

Note:  I found another possible cause of this error.  I had a situation where a function tool created a VString with a huge maximum character count, and even though most of those characters were null, cutting down the size to something like 20K allowed my flow to go.  It was failing at join time until I truncated the maximum length.
