CORB error when using Gitlab

[matfiz]

I have tried to use the extension with Gitlab. Login is ok, but then in the Google Script Editor, I'm getting an error in js console:

Cross-Origin Read Blocking (CORB) blocked cross-origin response https://gitlab.com/api/v4/groups?per_page=25&private_token=xxxxxxx with MIME type application/json. See https://www.chromestatus.com/feature/5629709824032768 for more details.

Shall I change some settings to whitelist the website?

Are you using gitlab.com or hosted gitlab?

Actually, I've tried on both. I started by modifying the manifest and adding my hosted gitlab url + uncommend the gitlab url. Then I've installed the plugin in chrome. Neither gitlab.com nor hosted gitlab works, both return this CORB error.
