Description Jonathan Druart 2022-07-12 08:08:13 UTC
DataTables is not raising error to the end user, it's only displaying a generic message in the console.
This leads to lot of questions on IRC or the mailing list ("the table is empty").
We can do better and display what went wrong.

We could also imagine add a link to the wiki for the more common problems (won't be implemented here however).

Test plan:
Revert "Bug 31104: Put each link on a separate header" and search for a
patron using a very long string
You should get an alert with the reponse of the server.
In my case:
"""
Something went wrong when loading the table.
414: Request-URI Too Long
"""

You can also make the REST API returns a 500 (bad specs or simply with a
die statement).

Comment 3 Martin Renvoize 2022-07-12 09:47:28 UTC
Works as designed.. signing off.

We could go a little further and grab our API error messages from 'responseJSON'.. but I'm not sure if would yield any better results in terms of people coming and asking for help.. we're still likely to need to ask for more details to really investigate any problems and as such direct them at the console and networking log to get those details anyway.
