Over time, Git deploy keys can get corrupted or deprecated, particularly those generated using older SHA-1 encryption (typically before June 2024).
When a key stops working, developers are unable to perform Git operations such as fetching branches, pulling, or committing changes in edit mode. The deployed version of your app will remain functional, but edit/development mode will continue showing errors like the one shown below until the key is renewed.
If your Git deploy key has expired, revoked or is still SHA-1 - you can easily generate and add a new one to re-establish the connection between your Git repository and Appsmith. In order to correct this situation, please follow the below steps:
Step 1: Go to your Git-Connected App
Step 2: Go to Git Settings
Step 3: Click on "Generate deploy key"
Step 4: Copy the newly generated SSH key
Step 5: Go to your repository settings
Step 6: Click on the "Deploy keys" menu
Step 7: Click on "Add deploy key"
Step 8: Give your new key a title, paste the generated SSH key, check "Allow write access", and click "Add key"
Step 9: Go back to your Appsmith app, check the box confirming you’ve added and enabled write access for the deploy key, then click "Finish"
