Hi everyone,
I'm currently developing a Custom Data Connector with the PKCE OAuth2 flow.
We are having some strange issues during a data refresh when an expired access_token is provided.
From Fiddler, we can see that the initial exchange for a new token occurs successfully. But shortly thereafter, multiple calls are made to the /token endpoint using the old refresh_token. It appears that the number of subsequent calls correlates to the number of queries/tables used.
Other observations:
I'm wondering if this is a known bug?
Other reference with exact same issue, which seems unresolved.
