Javascript error preventing gutenberg editor from loading.

Hey thanks for bringing this up but I believe this must be a gin issue and not sure if we should fix this in Gin itself or do a hotfix at gin_gutenberg. I'll follow this up over at Gin first. added the related issue here as well

The latest dev version of gin fixes the js error. however my gutenberg forms still wont load. I just get the spinning "loading" indicator

No errors are the in the js console.
It does work correctly when I switch the admin theme to something other than gin.

using the MR461 from 🐛 Save button missing when using the Gutenberg/Mercury editor module Fixed as a temporary fix gets this working for me for now.

With Drupal 10.3.1 and the MR here, I was able to get the editor working with Claro, but not with Gin: https://www.drupal.org/project/gutenberg/issues/3460790 🐛 Editor not loading (Drupal 10.3.1, Gutenberg 3.0.2) Active .

I get the TypeError mentioned in the description and an additional one:

TypeError: Cannot read properties of null (reading 'addEventListener')
    at Module.<anonymous> (gin_gutenberg.js?v=1.0.0:1:1058)
    at n (gin_gutenberg.js?v=1.0.0:1:110)
    at gin_gutenberg.js?v=1.0.0:1:902
    at gin_gutenberg.js?v=1.0.0:1:911

I got this to work again by adding the following patch to the Gin theme https://www.drupal.org/project/gin/issues/3460150 🐛 Save button missing when using the Gutenberg/Mercury editor module Fixed

Closing, the Gin issue should fix it.
