Uncaught (in promise) TypeError: i.includes is not a function when adding a block

Description

I am using a CK Editor field with Entry type blocks.

On 1 page, the single section for the homepage i'm getting a JS error when adding blocks to my CK Editor field. I have 3 languages: NL,FR and EN. I only get this error on EN and FR.

When adding the block I get an JS error in the console:

Uncaught (in promise) TypeError: i.includes is not a function at ElementEditor.js:1147:18

On other pages using the same setup/CK Editor field I don't get this error.

Expected behavior

On other pages when adding the block I can see the block added in the CK Editor field.

Actual behavior

No block is added, console gives me JS error.

Thanks for reporting that. Looks like it might be more of a Craft CMS issue despite happening in CKEditor so I transferred to the cms repo.

I can’t reproduce though, and looking at the code, I don’t understand how the error could occur. If you could send your database and Composer files into support@craftcms.com, we can look further into it from there.

I've sent the composer files and DB to support@craftcms.com. Let me know if you need anything else.

Thanks, received! Which entry are you getting the error on?

Thanks, received! Which entry are you getting the error on?

On the Home Single Section. For example in the CK Editor field (Column 2) on the first Block - Default when adding a Links block below the text.

Thanks! I was able to reproduce with your site, and got it fixed for the next release.

You can get the fix early by changing your craftcms/cms requirement in composer.json to:

"craftcms/cms": "5.x-dev as 5.5.0.1",

Craft 4.13.3 and 5.5.1 are out with that fix. Thanks again!
