We are also getting these errors. It started around 4-5 days ago.
None of the ad accounts we have are older than 15 months, most of them are (perhaps) a month old.
One example we've seen is a Google account which is an Admin in an AdWords Manager Account, which is valid and works as expected. It manages a Client Account that was created by another MA.
Also, a single Client Account (perhaps created before the Manager Account, perhaps after, but indeed created by the same Google account) is shown in the account selection UI as "Setup in progress".
This account setup process was started and aborted days if not weeks ago, and was never finished.
Calling the CustomerService (v201802) immediately returns an HTTP 500 error, with code:
'[AuthorizationError.CUSTOMER_NOT_ACTIVE @ ; trigger:\\'<null>\\']'
This is the code (Python):
adwordsClient = getAdwordsClient(refreshToken, clientCustomerId=None)
customerService = adwordsClient.GetService('CustomerService', version='v201802')
accounts = customerService.getCustomers()
So really, nothing special in the code. Not asking for a specific CA, just for the directly accessible customer accounts.
Thing is, the "Account in Setup" CA blocks us from seeing the MA which is completely valid.
This seems like the bug reported by MG.
Any way we can help?
Thanks,
Alon
