Occasional INVALID_REFRESH_TOKEN errors from Fantasy API?

Occasional INVALID_REFRESH_TOKEN errors from Fantasy API?

Every once in a while, an Oauth2 token that I have from the Yahoo Fantasy API stops allowing me to refresh it.  I will pass the refresh_token to the get_token end-point and the response will be:


{"error":"INVALID_REFRESH_TOKEN","error_description":"Failed to decode/encode refresh token"}


This is a token that I was previously able to refresh many times just fine.  And then suddenly it stops working.


(I think my previous post was deleted because I provided an example token, so I won't do that again, but I'd be happy to provide additional information if necessary.)


Thanks in advance!
