Hello,
We also had the same error but I don't know the cause. I can't reproduce it on a very simple report.
This error occurs on a complex report with a table control and several groups content.
Do you need the complex report that contains this error ?
Best regards,
@mterceno exact, happens only in complex reports and with groupings.
https://gist.githubusercontent.com/GlauberF/d6403fea9b5403e2afb44d1a7aea6e00/raw/34d1ec1c0f1e9e04bbbf6deb0b7632f1f6d93619/template.json
could you export the report template in a separate gist? the report template should be as small and simple as possible, so it is easier for us to reproduce the issue.
I could now extract the report template but with the test data included in the template the error does not occur. Could you export a report template with test data included which causes the error? this would make testing and fixing this issue much easier for us.
@alhman It is difficult to pass complex models, when the same problem, but the one I sent is causing a problem.
remembering that to test, you have to simulate that it is not a "isTestData":false test, but that you are passing real data.
And the data field, contains all the real data that generates the problem.
