Error when remove a role

Please try this patch.
Thanks

That's Ok now, no more error when I remove a role. Thanks !

Hi,

I can't reproduce the problem.

$this->authorized_roles, as well as $this->authorized_users for the case of user deletion, are empty arrays if I have not set specific roles or users to access the channel. And empty arrays do not provoke errors.

If you read the error message, it is written:

expects parameter 2 to be array, null given

So I guess that authorized_roles is not set at all in your channel configuration.

This is coming from a change introduced in 8.x-3.0-rc2 #3211003: Add more options for channel access → , which required to execute post_update hooks to ensure configuration is in a good state.

Have you tried to resave your channels configuration before deleting your role?

Closing to clean up the issues queue.

Feel free to re-open if able to provide steps to reproduce starting from a fresh standard Drupal install.

Hello,

Having no role configured in a channel should not cause an error when a role is removed.

Hi,

Absolutely, and this is not in opposition of what I had written in comment 6.

So I guess that authorized_roles is not set at all in your channel configuration.

This sentence does not mean you have no role configured in your channel, this means that I think the current config structure in your channels entity is not the expected one and you hould try to resave it and see if a difference appear.
