Is it possible to not have the warning or errors notices appear at all as shown in this screenshot?
I’m not aware of an option to suppress the notices, although avoiding warnings is sometimes a matter of choosing settings that avoid them. For example, access warnings can sometimes be avoided if using a –snapshot-policy is possible. Filters and careful source file data selection might also avoid some issues.
Errors are more severe than warnings, so more important that someone know about them, however the counter-argument is that there are lots of other reporting options available beyond a notice in a browser. Countering that is that the UI is where things get run, and any person running should know of run issues, however that argument weakens when there’s a scheduled task doing the runs (as you appear to have).
Possible to suppress warnings - only show “X” for Errors? was a feature request similar to this question.
