[Arsh]

Hey there,
We have been getting following error in response for some of our clients when pulling for change_event via change_event_service.
It has been more than a month now , kindly help us by getting this resolved.

I can reply with complete response and request log if required to speed up the process.

Thanks in advance :)

To add to that,
for this customerId, we get a successful response when we use a smaller daterange (last 7 days from today say). Seems like it has to do with a specific type of change happening in the account maybe? 

Thanks!

Hi,

Thank you for reaching out.

However, I had to delete your initial post as it contained details of your logs.

Moving forward, an internal error usually indicates a temporary issue or a bug. So our team can investigate further, could you provide the customer IDs involved and also their respective and complete request and response logs, with the request-id?

If logging is not yet enabled, you may do so by navigating to the Client libraries > Your client library (ex. Java) > Logging documentation, which you can access from this link.

You may then send all the requested details using the Reply privately to author option.

Best regards,

Hi Arshdeep,

This looks like a server-side issue at our end. I was able to pull the relevant log and pass it onto the team for further investigation. I'll keep you posted as I hear from them.

Cheers

Great! Thank you for the update.

Looking forward to hearing from you.

Hi there, 
We are no longer getting the specified error so I believe the issue has been resolved.

That being said, there is a difference in count in results returned in ChangeStatus service vs Change Event service for the same date range.
Also, the change Event service events count (like for the resourceType 'ads'), doesn't seem to match with what we could see in the Google Ads interface for the same DateRange.

Is that expected, if not I can raise a separate concern, since this thread is not related.

Hi Arshdeep,

I think this behaviour is expected. ChangeStatus service is a summary view, so it tells you what entities have changed. The expectation is that you use this detail to download the object again. ChangeEvent service is a detailed view, so it tells you what the specific changes are. You can use it to figure out what changed in an entity. 

We try to make all changes available through this service, but it is always not guaranteed. The Google Ads UI is typically the first to introduce a new feature (and hence a change type), and it may get added to the API afterwards. So if there are specific change events that are missing in the API, please share the details and we can take a look to see why the API isn't returning it, but the UI is.
