Error: Argument #1 ($event) must be of type object

Hi, i confirm the same problem in Drupal 10 with PHP 8.1. and the dev version of the module.
It needs to push twice to change the state of the flag.

I am seeing this error also since moving from Drupal 9.5 to 10.

My flags and rules were working perfectly in 9.5 but now one flag has to be clicked twice, and another goes to an error page "The website encountered an unexpected error. Please try again later." Then clicking the flag appears to not execute the rule.

Hi,
I have fixed the above error "Error: Argument #1 ($event) must be of type object", please check the solution in raised MR.
Thanks.

I am getting the same thing. Is there a patch I am missing?

The website encountered an unexpected error. Try again later.

I am on:

• Drupal 10.2.2
• Rules 8.x-3.0-alpha8+2-dev
• Rules Flag 1.0.2+1-dev

I install the Rules flag module and try to flag an ECK entity and get the above WSOD error. Refresh the screen and entity displays fine and is flagged like it should be. When I unflag it, error shows back up. NO rules written yet. Example Rules have also been disabled.

Uninstall the module and flagging works a designed.

I am migrating a site that relied a lot on Rules and Flags. Is there any chance someone can help me find a solution?

I think I figured it out. Looks like maybe the arguments in lines 23, 32, and 45 are in the wrong order. Changed them to the following and things look to be working.

23    $event_dispatcher->dispatch($event, UserFlaggedEvent::EVENT_NAME);

32  $event_dispatcher->dispatch($event, "rules_flag_entity_flagged:$entity_type");

45  $event_dispatcher->dispatch($event, "rules_flag_entity_unflagged:$entity_type");

I know just enough to be a little useful sometimes. Never wrote a patch, so if someone could handle that end, that would be cool!

Hope this helps!

tawellman's edits to rules_flag.module (for me ver 1.0.3) are also working on my sites.

I also don't know how to roll patches the git way. I see instructions here → and here → , but I currently manage a single public website and one dev version... so it has not made sense to learn Git just for that.
... likewise for interdiff → and drupalorg-cli.

But here's an old fashioned diff patch.

the rout cause is the change in Drupal core 9.1 https://www.drupal.org/project/drupal/issues/3055194 →
