workflow suddenly does not work - but no error messages in debug

Hi - has anyone had an issue where you had a workflow working for over a year then suddenly it doesn’t. I ran it in August and everything was fine. I ran it last week and it isn’t working. No changes to workflow either. I run it through debug and it seems to work fine. By working, I mean I get a .pdf output size 1kb ( not valid pdf). If i run it through debug, the pdf is fine.

Any suggestions?

Thank you!

UPDATE - Prior to posting tis - I ran five xml files. All pdf’s output were bad. Then after, I ran one xml file through and it was a good pdf. Then I ran three and pdf’s were good. Then I ran all 25 files through again and the output pdf’s are all good.

While it seems to be working now. I am still interested to hear if anyone has experienced this.

Hi, I would suggest you to verify that the data positions did not changed slightly. Maybe a data is not retrieved correctly in production mode (carriage return in it for example). Do you get the same issue with an old data file?

When you go through your logs, can you trace the whole process and according to the logs, everything is happening as it is supposed to?

Yes - when I went through the logs. Everything was as it should be. At first I thought maybe the data files were getting picked up to fast. But if that was happening wouldn’t it produce an error instead of a bad pdf?

When it reaches the steps here it creates the PDF,what do you see in the logs?

If all is working as it should, then you would see the PDF created and stored somewhere…no?
