getCustomers() returns AuthenticationError.CUSTOMER_NOT_FOUND in some cases

[Ondřej P]

Hi there,

I use getCustomers() operation (without clientCustomerId in request header) for getting list of user's customers, but in some cases I get following error:

I know that our authenticated user has an AdWords account, I tried to call the same request for 3 days but with the same result. I tried to revoke and get new refresh token as well. We use getCustomers() operation for each of our users and we detected this issue at around 10% of our users - it works fine for the rest of our users. Can you check this issue please?

Thank you,

Ondřej
