Gitlab PKCE auth error on Decap 3.1

kkellydesign commented 10 months ago

As of the Decap 3.1 release on February 1, Gitlab PKCE is no longer working. I've tested both Firefox and Chrome.

When I visit /admin and try to log in, it immediately redirects me to Gitlab and shows the following screen:

To Reproduce config.yml:

backend:
  name: gitlab
  repo: my_repo # Path to your GitHub repository
  auth_type: pkce
  branch: main
  app_id: my_id

admin/index.html – the link below causes the error. But changing the pinned version to 3.1.0-beta.2 fixes it.

     <script src="https://unpkg.com/decap-cms@3.1.1/dist/decap-cms.js"></script>

    <script src="/dist/js/nunjucks-slim.js"></script>
    <script src="/admin/util-bundled.js"></script>
    <script src="/admin/templates.js"></script>
    <script src="/admin/previews.js" type="text/babel"></script>

Applicable Versions:

Decap CMS version: 3.1.1
Git provider: Gitlab PKCE auth
OS: mac locally.. but also on prod, with the CI running on Gitlab.

I suspected https://github.com/decaporg/decap-cms/pull/7014 break gitlab PKCE.

Closed by automation - please test and reopen if patch 3.1.2 does not fix this. Thanks @blackb1rd
