Hello, We have been using refresh token to access ads entities. However, we recently notice that there are several times when the refresh token got invalidated. Below are two types of message that we got when we try to call AdsOAuthProvider::RefreshAccessToken(). Based on the fact that we have been using the same refresh token, we think the token was somehow invalidated.
Can you please help to check: 1. What do the two types of error message mean? In which scenario do they show up? 2. Is there a way to check the root cause of the invalidated token (assuming that the token was invalidated)? If so, what information do you need to start the investigation? Thanks, Gavin Exception: Google.Api.Ads.Common.Lib.AdsOAuthException: Failed to refresh access token. ---> System.AggregateException: One or more errors occurred. ---> Google.Apis.Auth.OAuth2.Responses.TokenResponseException: Error:"invalid_grant", Description:"Token has been expired or revoked.", Uri:"" at Google.Apis.Auth.OAuth2.Requests.TokenRequestExtenstions.<ExecuteAsync>d__0.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Google.Apis.Auth.OAuth2.Flows.AuthorizationCodeFlow.<FetchTokenAsync>d__35.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at Google.Apis.Auth.OAuth2.Flows.AuthorizationCodeFlow.<FetchTokenAsync>d__35.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Google.Apis.Auth.OAuth2.Flows.AuthorizationCodeFlow.<RefreshTokenAsync>d__31.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Google.Apis.Auth.OAuth2.UserCredential.<RefreshTokenAsync>d__16.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Google.Apis.Auth.OAuth2.TokenRefreshManager.<RefreshTokenAsync>d__12.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Google.Apis.Auth.OAuth2.TokenRefreshManager.<GetAccessTokenForRequestAsync>d__10.MoveNext() --- End of inner exception stack trace --- at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions) at System.Threading.Tasks.Task.Wait(Int32 millisecondsTimeout, CancellationToken cancellationToken) at Google.Api.Ads.Common.OAuth.AdsOAuthProviderImpl.GetAccessTokenForAuthorizationCodeFlow() at Google.Api.Ads.Common.OAuth.AdsOAuthProviderImpl.RefreshAccessTokenInOfflineMode() --- End of inner exception stack trace --- at Google.Api.Ads.Common.OAuth.AdsOAuthProviderImpl.RefreshAccessTokenInOfflineMode() Couldn't get fresh tokens.
