Question
You are trying to continuously deploy from GitHub to Azure, but receive a “Cannot find SourceControlToken with name GitHub” exception. What is the explanation of this error?
A. Azure did not receive an (Open Authorization) OAuth token
B. Azure did not receive a service principal
C. Azure did not receive a control principal
D. Azure did not acquire a JSON Web Token (JWT)
Answer
A. Azure did not receive an (Open Authorization) OAuth token
Explanation
The error “Cannot find SourceControlToken with name GitHub” occurs because Azure App Service is unable to locate or authenticate an OAuth token required for integrating with a GitHub repository. This token is essential for enabling continuous deployment from GitHub to Azure.
OAuth Token Missing or Misconfigured
The error indicates that Azure cannot find the necessary OAuth token, which is used to authenticate and access your GitHub repository. Without this token, Azure cannot establish the connection needed for deployment.
Common Causes
- The OAuth token was not generated or linked correctly in GitHub.
- The token lacks the required permissions (e.g., “repo” scope for private repositories).
- The Deployment Center in Azure was not properly set up to use the token.
Steps to Resolve the Issue
Step 1: Generate a Personal Access Token (PAT) in GitHub
Go to GitHub Settings > Developer Settings > Personal Access Tokens.
Create a new token and ensure it has the “repo” scope for accessing repositories.
Step 2: Reconfigure Deployment Center in Azure
In the Azure Portal, navigate to your App Service and open the Deployment Center.
Select “GitHub” as the source control provider and log in using your GitHub credentials.
When prompted, provide the newly created PAT as the Source Control Token.
Step 3: Reauthorize OAuth Applications
Check if Azure App Service is listed under Authorized OAuth Apps in your GitHub account settings.
If necessary, revoke and reauthorize access to refresh the connection.
Step 4: Wait for Synchronization
After setting up, allow some time (15–20 minutes) for Azure and GitHub to synchronize resources before retrying deployment.
Key Takeaways
- This issue arises due to missing or invalid OAuth tokens.
- Properly configuring and authorizing a personal access token resolves the error.
- Always ensure your tokens have adequate permissions and are correctly linked in both platforms.
By following these steps, you can successfully enable continuous deployment from GitHub to Azure without encountering this error.
