Hello,

I've got running locally within an instance of Docusaurus. Everything works perfectly (and looks great), however when I commit to GitLab, then try to deploy on GitLab pages I get the following error from the CI runner:

Any help would be greatly appreciated!

Nevermind. This appears to be non-Redoc related.

Did you find a solution for this? I am running into the same issue and it happened after adding ReDoc to my docusaurus site

I have exactly the same issue. After adding ReDoc to docusaurus v2 I get this issue and builds fail.
The solution that worked for me was using the ProviderPlugin as mentioned webpack/changelog-v5#10
