I have a solution run with WebDirect. Authors need exported files in .xlsx format so I have a script and in that script call a PSOS that creates the .xlsx file and inserts it into a container. Then the script continues and Exports Field Contents of the container. When I run the script I sometimes get the message below and no file is exported. I can click the button to trigger the script again and it will run fine. I tried adding a Pause in the PSOS part of the script thinking maybe it was taking a while to place the file into the container but that didn't help. Any ideas on why I'd get this message every other time?
