No, I did not do something regarding the error. However, upon further checking with the team, the
TargetingIdeaService is more expensive service compared to the other AdWords API services.
The rate limits for this service can vary based on the time of day, overall volume of API usage by all users, and other factors. Therefore, this is not dependent alone in your QPS in your account, but to other accounts as well by all users.
This said, if you encounter again the RateExceededError with rateScope=ACCOUNT for this service, then the only way to minimize this issue is to
slow down and retry your request based on the number of seconds specified in the retryAfterSeconds field of your response.
