Hi @tsteur, thanks for the back trace.

Using the provided URL on a local instance this works for me without error, both with and without data present.

From the code it looks like the datatable might be passing the 'hasAnyData()` check but doesn't actually have any returnable rows. Might be something specific to the data.

Can the issue be recreated consistently or with any other dataset?

I can definitely reproduce it in that specific account. Viewing the report via the UI works. Exporting as XML and HTML too. After digging deeper seeing this might be actually caused by a special plugin of ours where it fetches data from the demo site. I'll close this one and will create an internal Jira issue.

Thanks for that 💯
