Hi,
I'm receiving the following error: Using AdWords API v201809
error: Creating Billing Account for xxxx-xxxx-xxxx-3207 Google Error. Error: AdWordsApiException: Exception of type 'Google.Api.Ads.Adwrods.Lib.AdWordsApiException' was thrown.. (Error.BudgetOrderError.UNKNOWN, FieldPath: operations[0].operand.startDateTime.endDateTime,Trigger:no billing setup found, may be in the middle of signup.
The error indicates that the billing is not set up, but it clearly is. I have not changed the code that uses the BudgetOrderService and it was working great. It stopped working a couple of weeks ago.
I cannot replicate this error using our test account, because as you know the BudgetOrderService will not work with test accounts. I do not have any soap logging to supply you. I can however supply you will the billing account and the customerId so you can investigate.
