slow response time when calling Dropbox.Api (6.37.0) with expired access token
Hello. I am calling an established Dropbox account setup for an application with API access with what was once a valid access token that has expired. It takes about 15 seconds or more to obtain the...
Thanks for the report. It looks like the .NET SDK is unnecessarily retrying (repeatedly, with a backoff) on 'expired_access_token' failures. I'll ask the team to update it to skip the automatic retries on that kind of failure.
To work around this, you can make a DropboxClientConfig with maxRetriesOnError set to 0, and pass that to DropboxClient. That would prevent the automatic retries and eliminate the extra latency in this case. It would also prevent the automatic retries in cases where they may be useful though, so if you want to lower that extra latency without completely disabling automatic retries, you can set it to a number between 0 and 4 (since 4 is the default).

Thanks for the quick reply. Yes, your solution / workaround did make the response time better with using MaxRetriesOnError set to zero. I am still seeing response times of 6 to 12 seconds with this change. Seems like it should be 50% of the response times I am seeing when passing an expired token.
