Hey there! Let's figure out why your migration from v201710 to v201802 isn't working, even though you followed the same version-switch step as before. Here are actionable steps to get things back on track:

1. Check for Unnoticed Breaking Changes #

Even small version jumps can include subtle breaking changes that aren't obvious at first glance. Some things to verify:

• Removed/Renamed Fields: Certain fields (like reporting metrics or campaign settings) might have been deprecated or renamed in v201802. Double-check if any fields you're referencing in requests/responses were updated in the v201802 API reference.
• Service Endpoint Adjustments: While rare, some service paths might have changed alongside the version. Confirm your code is targeting the correct endpoints for v201802.
• Scoping Changes: Ensure your OAuth2 credentials have the necessary scopes for the v201802 API (though this is usually backward-compatible, it's worth a quick check).

2. Verify v201802 is Enabled for Your Project #

Newer API versions sometimes need explicit enabling in your Google Ads API console:

• Log into your Google Ads API dashboard.
• Navigate to your project's API settings and check if v201802 is listed as an enabled version.
• If it's missing, enable it and retry your code.

3. Update Your Client Library (If Using One) #

If you're relying on an official client library (like Python's googleads or Java's client library), just changing the version = 'v201802' parameter isn't enough. The library itself needs to support the new version:

• For Python: Run pip install --upgrade googleads to get the latest compatible version.
• For other languages: Download the latest library release that explicitly supports v201802.

4. Capture and Analyze Exact Error Messages #

"Not running normally" is vague—debugging requires specific error details. Add verbose logging to your code to capture API response errors. Common issues you might see:

• FieldNotFoundError: Indicates a field you're using was removed in v201802.
• AuthenticationError: Your credentials might not be properly configured for the new version.
• InvalidOperationError: A request structure that worked in v201710 is no longer valid in v201802.

5. Test with a Minimal Working Example #

Isolate the problem by creating a simple test script that only performs a basic operation (like fetching account info or a single campaign) using v201802. If this works, the issue is in your existing code's specific requests, not the version switch itself. This helps narrow down which part of your code needs adjustment.

6. Validate Request Payloads Against v201802 Schema #

Cross-check your request structures against the v201802 API specs. For example, if you're mutating campaigns, ensure all required fields are present and formatted correctly as per the new version's schema. Even small changes (like a field's data type) can cause failures.
