This KB Article solved the issue : Error log throwing up "null: no thrown error" when loading certain Dashboards :
Resolution
Following steps can be taken to avoid these errors in the system logs:
- Ensure that all the objects used in the dashboard (such as reports, PA widgets, content blocks, and other widgets) are brought over to the target instance.
- If some error still show up after bringing across all the configurations and the dashboard itself is not having any issues except for the errors appearing in the logs, deleting all the sys_grid_canvas_pane records having invalid references returned by the following URL should get rid of the errors in the logs.
Note:
- Take an XML backup of the records before deleting them so that you can revert in case of any issues.
- Please test the solution on a recently cloned instance before applying any solution on the production instance.

Hi Christian,
that seems error message generated by system; but I could not find any documentation around that
Mark ✅ Correct if this solves your issue and also mark 👍 Helpful if you find my response worthy based on the impact.
Thanks

I get this error as well, probably due to the reason of using XML to transfer the dashboard...
Problem is, development has already gotten a refresh from production, so I don't have the original 'dashboard configuration'.
Is there any way to solve this now?

Hello,
If the dashboard works as expected and all the related records is present, then you could delete the sys_grid_canvas_pane records.
