Hi there, thanks a lot for your all the work Netlify is doing to build a better web 
I’m trying to implement Netlify CMS for a Jekyll static site whom repo is on a self-hosted gitlab instance.
I’ve followed your documentation. Created an app in gitlab on instance level with “api” permission.
When I go on mywebsite/admin/ the login screen shows, it seems to go smooth and I get to the CMS dashboard.
But every collection is empty. I thought it came from my config.yml but it seems right. Then I checked the browser console on the admin page and there it is :
failed to load file from GitLab: _data/nav.yml implementation.js:42:16
API_ERROR:
cms %5E2.0.0/dist/netlify-cms.js:51
cms %5E2.0.0/dist/netlify-cms.js:51
cms %5E2.0.0/dist/netlify-cms.js:208
entries.js:882:14
persistEntry entries.js:882
It says a similar message for every static file I point to. It doesn’t write any error for folders, although they look empty.
Then I tried to create a author and I get that error in the console :
API_ERROR:
cms %5E2.0.0/dist/netlify-cms.js:51
cms %5E2.0.0/dist/netlify-cms.js:51
cms %5E2.0.0/dist/netlify-cms.js:208
[entries.js:882:14](webpack://NetlifyCms/.-core/dist/esm/actions/entries.js)
persistEntry entries.js:882
So it looks like there’s a permission or access issue somewhere.
My config.yml backend section looks like that :
backend:
name: gitlab
repo: indiehost/website
branch: add-blog-and-cms
auth_type: implicit # Required for implicit grant
app_id: xxxxxx
api_root: https://git.indie.host/api/v4
base_url: https://git.indie.host
auth_endpoint: oauth/authorize
site_domain: https://web2.beta.liiib.re
For info, I’m working on “add-blog-and-cms” branch for the moment and will merge when everythink working to master. authors, post and all are on ‘add-blog-and-cms’ branch at the moment.
In Gitlab, the app is instance-level and has settings:
URI: https://web2.beta.liiib.re/admin/
Trusted : true
Confidential : true
Scopes : api
I have no more idea to make it work 
Please help
