Current Behavior

When trying to use the ADO git provider I get this error:

{
  "message":"Internal error exchanging Oauth code.",
  "detail":"oauth2: cannot fetch token: 400 Bad Request\nResponse: {\"Error\":\"invalid_client\",\"ErrorDescription\":\"Failed to deserialize the JsonWebToken object.\"}"
}

Expected Behavior

The git provider successfully retrieves an access token.

Very odd... can you post the configuration you have for the Git auth provider? (without valid creds of course)

This is the values.yaml for the auth provider:

coder:
  env: 
    - name: CODER_GITAUTH_0_ID
      value: "primary-azure-devops"

    - name: CODER_GITAUTH_0_TYPE
      value: "azure-devops"

    - name: CODER_GITAUTH_0_SCOPES
      value: "vso.code_full vso.tokenadministration"

    - name: CODER_GITAUTH_0_CLIENT_ID
      value: "..."

    - name: CODER_GITAUTH_0_CLIENT_SECRET
      valueFrom:
        secretKeyRef:
          name: coder-secrets
          key: CODER_GITAUTH_ADO_CLIENT_SECRET

    - name: CODER_GITAUTH_0_AUTH_URL
      value: "https://app.vssps.visualstudio.com/oauth2/authorize"

    - name: CODER_GITAUTH_0_TOKEN_URL
      value: "https://app.vssps.visualstudio.com/oauth2/token"

It's worth noting that I got Github to work as a git provider without any issues.

The problem was that I accidentally used the App Secret instead of Client Secret for the Azure Devops App.

I've created a PR to add a bit more detail to the docs #6923
