Incompatibility with Devel

Hi @joncjordan,

Thanks for reporting. I can reproduce a similar issue.

The website encountered an unexpected error. Try again later.

Symfony\Component\Routing\Exception\MissingMandatoryParametersException: Some mandatory parameters are missing ("machine_name", "step") to generate a URL for route "entity.memory_limit_policy.devel_load". in Drupal\Core\Routing\UrlGenerator->doGenerate() (line 187 of core/lib/Drupal/Core/Routing/UrlGenerator.php).

It seems devel is trying to add its own route to debug the entity. I need to check why it fails as I do expect this to be very generic and applied to all kind of entity types.

I feel this is some incompatibility between Devel and EntityWizard from Ctools which is used to generate the multistep form.

I don't think the multistep form add so much value and I was already wondering about removing Ctools dependency to ease the maintenance.

I will create a specific ticket to remove Ctools dependency and leave this bug open to remember to check it is fixed after Ctools removal.

I have raised a Draft MR in #3444342 📌 Remove ctools dependency Active which remove Ctools.

I can't reproduce the issue anymore and I can see the "Devel" operation in the policy dropdown button.

I need to perform some more tests before merging the MR and creating a new release.

Thanks for looking into it. I've been away from the office but I can help review when I'm back.

I did some more testing and I am not able to replicate anymore after the last change (removal of ctools). It is merged in 2.x.

Please reopen if you still face the issue.
