OAuth 2 returning 401 error randomly

{“success”:false,“error”:“Invalid token: access token is invalid”,“errorCode”:401}

We have an app in the marketplace, sometimes for some users randomly receiving this error even if the access_token not expired.

Please assist

Can you please tell me which app is it, what’s the clientid and more details about the error itself?

Timeframe of the error
company id and user id of the user

You can share those with me directly or you can reach out to marketplace.devs@pipedrive.com
