Export To Excel - Couldn't Download Network Issue

Certified Senior Developer

I can't find my exact issue, so I'm starting a new thread. 

I created two interfaces - one that shows a single survey and its answers in a grid and the user can download the data to Excel. That works fine. Then I made a copy of the interface and instead of filtering on a survey the grid displays ALL surveys and answers. However, when you try to export to Excel, I get the error "Couldn't Download - Network Issue". The number of records is LESS THAN  20 and so it's not a size issue.

This happens in the DEV environment. I haven't tried it in the TEST environment because I'm not ready to push my code yet.

Any thoughts why?

    Yes, thank you for the suggestion. The tomcat-stdOut.log file proved to show the issue. It was a comma inside the bracket for my call to a field in my record type
