It looks like you're encountering an issue with the Google Search Console connector in Airbyte OSS where the service account credentials are not being accepted. Here are some steps and considerations to help troubleshoot and resolve this issue: ### Steps to Troubleshoot 1. Verify Service Account Credentials: Ensure that the JSON key file for the service account is correctly generated and contains all necessary information. Follow these steps to create and verify the service account: - Open the [Service Accounts page](https://console.developers.google.com/iam-admin/serviceaccounts). - Select your project and create a new service account if you haven't already. - Assign the Viewer role to the service account. - Generate a new JSON key file and download it. This file should contain fields like

type

,

project_id

,

private_key_id

,

private_key

, etc. For detailed steps, refer to the [Google service account with JSON key file setup guide](https://docs.airbyte.com/integrations/sources/google-search-console#google-service-account-with-json-key-file-recommended-for-airbyte-open-source). 2. Check Permissions: Ensure that the service account has the necessary permissions to access the Google Search Console API. The service account should have at least Viewer permissions. 3. Enable Google Search Console API: Make sure that the Google Search Console API is enabled for your project. You can do this from the [API Console](https://console.cloud.google.com/apis/credentials). 4. Validate JSON Key Format: Ensure that the JSON key file is correctly formatted and contains no errors. The key should start with:

json    {      "type": "service_account",      "project_id": "YOUR_PROJECT_ID",      "private_key_id": "YOUR_PRIVATE_KEY_ID",      "private_key": "YOUR_PRIVATE_KEY",      ...    }

### Common Issues and Solutions - Invalid Credentials: If the credentials are invalid, you might see errors like

UnauthorizedServiceAccountError

. Double-check the JSON key file and ensure it matches the service account you created. - Domain Validation Error: If you encounter errors related to domain validation, such as

InvalidSiteURLValidationError

, it might be due to insufficient permissions or incorrect site URLs. Ensure that the site URLs you are trying to access are verified in Google Search Console. - Version Compatibility: Sometimes, specific versions of the connector might have issues. If you are using an older version, consider updating to the latest version of the Google Search Console connector. ### Example Error and Solution From the forum post, a user experienced a similar issue and resolved it by ensuring the credentials were correct: > "I believe the credentials I was inputting were invalid, I have managed to successfully connect now with both old and new versions."
