Hi,

Without any code changes in a report, I get this error :

```auto
2024-10-15 09:55:05 Traceback (most recent call last):

2024-10-15 09:55:05 RuntimeError: Undetected access error

```

and a lot of #ERROR in the list view but not linked to a record in particular.  
If I filter little part of the report by filtering in the context, I have no error…

Any ideas ?  
Tks  
Laurent

The query of the report is an Union of 2 queries, if I execute the report with the 2 queries separatly, it works. Changing all\_ parameter to False or True has no impact.

This is typical of table query that does not generate unique `id`.
