Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'wrongRequestId')

📝 Provide detailed reproduction steps (if any)

I'm using 34.2.0 version of ckeditor 5 with real time collab plugins. Also using the 4.0 ckeditor5-vue2 integration. I've tested 34.0 and 34.1 with the same javascript error. I see a javascript error in the cloudservicesrevisionhistoryadapter.js file. The Revision History does work properly but this javascript error comes up on first instantiation.

✔️ Expected result

Not see error in javascript console.

❌ Actual result

When using Revision History Realtime collab plugin, I see the following javascript error.

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'wrongRequestId')
    at cloudservicesrevisionhistoryadapter.js:23:4079

❓ Possible solution

Code is obfuscated so I cannot see what wrongRequestId means in this context.
