I am also experiencing the same issue, using the Java client library. I
have been successfully accessing the Ads API to pull reports for multiple
client customers via the 'search' endpoint for the last month or so.
Starting this morning intermittent 'UNAUTHENTICATED' errors began occurring
unpredictably. By unpredictably, I mean:
-API requests using the same immutable Credentials object succeed both
prior to and subsequent to the error.
-If a failed API request is repeated, it may succeed or may fail again.
These errors seem to occur on roughly 10% of API requests. Example:
19/04/26 10:51:19 WARN summary: FAILURE REQUEST SUMMARY. Method: google.ads.
googleads.v1.services.GoogleAdsService/Search, Endpoint: googleads.
googleapis.com:443, CustomerID: xxxxxxxxx, RequestID: dVfS-CY45L7gCmsbebvunw
, ResponseCode: UNAUTHENTICATED, Fault: Request is missing required
authentication credential. Expected OAuth 2 access token, login cookie or
other valid authentication credential. See https:
//developers.google.com/identity/sign-in/web/devconsole-project..
19/04/26 10:51:19 WARN AdWordsLogIngestion: Exception checking status for
customer xxxxxxxxx
com.google.ads.googleads.v1.errors.GoogleAdsException: errors {
error_code {
authentication_error: AUTHENTICATION_ERROR
}
message: "Authentication of the request failed."
}
at com.google.ads.googleads.v1.errors.GoogleAdsException$Factory.
createException(GoogleAdsException.java:42)
at com.google.ads.googleads.v1.errors.GoogleAdsException$Factory.
createException(GoogleAdsException.java:34)
Again, we have not had any issues accessing the API until this morning. No
code or environment changes on our end. Please let me know if you need any
more info.
