UI Grid error when DAG has been removed

[pierrejeambrun]

Reproduce on main:

• Run a DAG
• Rename the DAG
• Wait for dag file processor to remove the deleted DAG and add the new one. (Old Dag should not appear on the home page anymore)
• Go to the Browse DAGRUN page.
• Click on a DagRun of the deleted DAG, as if you want to see the 'details/grid' of that old dag run

Not sure it is some problem with my local setup or something else, but i am not able to reproduce

Did you run it with breeze ? Or ran the webserver in debug mode ?

We see that there is an error, you just don’t have the stack trace, meaning that the server is not in debug mode.

Having an error is not expected.

Yes. As mentioned in the first line of what you should do "gather the relevant information (detailed log with errors...".

You need to look there. Exposing more information in the UI is a potential security issue. No application in produciton mode should EVER do that.

I ran using breeze start-airflow, it won't occur there?

Oh okay.

You can add --dev-mode flag when you run start-airflow - then instead of the "ooops" screen you will see the screen that @pierrejeambrun posted above - with more details and debugging capabilities
