1) Symfony\Bundle\WebProfilerBundle\Tests\Controller\ProfilerControllerTest::testPanelActionWithLatestToken
UnexpectedValueException: The profiler template "@WebProfiler/Collector/command.html.twig" for data collector "command" does not exist.

Two choices:

• either the command profiler template is missing in this folder
• either the definition of the collector must be deleted

  ".data_collector.command" => array:2 [
    0 => "command"
    1 => "@WebProfiler/Collector/command.html.twig"
  ]

The change should be done in 6.4 ideally /cc @HeahDude

It seems WebProfilerBundle 5.4 cannot be compatible with FrameworkBundle 6.4, the latter being responsible for configuring collectors.

I see tow options:

• add a compiler pass in WebProfilerBundle 5.4 to remove new data collectors introduced by 6.x (I guess we will have the same error with the Workflow data collector if we fix this only for the command data collector).
• add a conflict rule in FrameworkBundle 6.4 to not allow WebProfilerBundle < 6.4.

I would go for the second solution.

Patching 5.4 to account for 6.4 would be wrong, so solution 2 would be the way. Ideally, I'd prefer FWB to not know about WPB. Is there no solution that doesn't involve adding any conflict line?

See #52218.

The conflict line was already there because I guess the problem was always there, adding collectors in FWB while adding templates in WebProfilerBundle.

So we can close here I guess.
