Refresh Token expired

[bszt123]

Hello,

We are issuing and using refresh tokens in our service according to the reference documentation below : 

Solved: Oauth2 refresh token question - what happens when ... - Dropbox Community (dropboxforum.com)

We understand that the refresh token should not expire, but it seems to expire after some time.

AuthError('a68526c2f28846df81b4e4290cc0567f', AuthError('expired_access_token', None))

AuthError('731de6b9ff3b4d828e2c538493dbc3fb', AuthError('expired_access_token', None))

AuthError('10bdfac6098247088d1684a7af1761c7', AuthError('expired_access_token', None))

AuthError('9ad81d2298104e63b5aa1e70de5a9fe4', AuthError('expired_access_token', None))

AuthError('57ac76c52e71491594bac208f8e239ca', AuthError('expired_access_token', None))

We would like to verify if we are issuing the tokens correctly.

Thank you.

Hm.. 🤔 As seems, somebody needs new glasses. As far as I can see, messages are about expired access token, not about expired refresh token. 🤷 Who knows... @bszt123  can you take a look again? You likely don't need glasses (not new at least). 😉

Good luck.

@bszt123 Здравко is correct; this error is referring to the access token being expired, not the refresh token. When you get this 'expired_access_token' error, you should use the refresh token to get a new access token. If you're using a Dropbox SDK, the SDK will do this for you automatically, as long as you supplied the necessary credentials (e.g., app key, app secret (if not using PKCE), and refresh token).
