Javascript Errors in Drupal 10.1

@gabykule
One of solution is to update core drupal as patch fix weight of dependencies in aggregation engine
There is 10.1 update too.
I combine too #2990907 issue if this can help.
Pleas check if this two patch fix issue

This is happening because Drupal 10.1 trying to aggregate the minified/aggregated js files from modules/projects.

This seems to only occur with JS aggregation on. Here is quick workaround to disable JS aggregation only for Gutenberg libraries until there is an official solution.

/**
 * Implements hook_library_info_alter().
 */
function MODULENAME_library_info_alter(&$libraries, $extension) {
  if ($extension === 'gutenberg') {
    foreach ($libraries as $name => &$library) {
      if (empty($library['js'])) {
        continue;
      }

      foreach ($library['js'] as $file => &$properties) {
        $properties['minified'] = TRUE;
        $properties['preprocess'] = FALSE;
      }
    }
  }
}

The solution stefan.butura suggested worked fine for our project

This is issue related to Drupal Core issue/bug in JS aggregation. May be resolved in next update. Till that it can be used without any code or patch by disabling Aggregate JavaScript files.

Step: Administration-> Configuration ->Development -> Performance and disable Aggregate JavaScript files.

It indeed seems to be related to the Drupal core issue in #2990907: JsOptimizer preg_replace gives null as return.

Since it's not recommendable to disable JS aggregation for the whole site the workaround in #6 just seem to be perfect. Here's a patch for it.

Since Drupal core issue has not gotten much attention, we might need to add this workaround to the module. Since it only affects the backend, it sounds absolutely alright to just disable aggregation for them.

Thanks for your contributions.

The patch at #10 is looking good. I'm running with it in 2 environments at the moment and both apply fine.

+1 for RTBC.

Just tried the patch that disables JS aggregation for Gutenberg libraries, and I confirm it worked for resolving JS Errors when using Gutenberg in Drupal 10.

+1 for RTBC as well.

Thank you for your contributions. This has been committed to dev.

Thanks for the fix!

How about a release for this one? Isn't it critical if the editor does not load at all?

We have been hoping for bigger attention on the underlying core issue, but it ended up in a new Gutenberg release 8.x-2.8 now :)
