UNEXPECTED_INTERNAL_API_ERROR when calling AdGroupCriterionService

[Caihua Du]

Hi there, 

We monitored that AdGroupCriterionService will throw "UNEXPECTED_INTERNAL_API_ERROR" lately across different customers. Is that any known issue from AdWords side? Thanks!

Google.Api.Ads.AdWords.Lib.AdWordsApiException: AdWordsApiException: One or more AdWords API errors have occurred. 

API encountered an unexpected internal error.. (Error: InternalApiError.UNEXPECTED_INTERNAL_API_ERROR, FieldPath: , Trigger: )

Hi Caihua, 

We are not aware of any issues at the moment. Could you please enable logging and share the complete SOAP request and response log for this operation? 

Thanks,

Thanks Sreelakshmi. The issue seems auto recovered and only last for a few mins (which cause about 10+ request failures). I will report again if I see more instances. 

Thanks,

Caihua.
