Sure thing @joeBumbaca
What i do is set up the Custom Auth. Then i "Auth" with it, and then switch between the OAuth2 and the Custom Auth, since the OAUTH2_TOKEN variable is already set up on the Resource side.
This is a PUT request - On GET ones, this behavior usually doesn't happen, but queries take somewhat longer in general as the whole App is immediately slower when i switch to the Custom Auth
The query with regular OAuth 2
And the same one with Custom Auth (OAuth 2 Generic)
Please note that on the server side, the request itself takes ~1 second. However, i see that there is around a 30-60 second difference between when i run the query on Retool until i actually get the request to the server. This behavior does not occur when using OAuth2, only while using the Custom Auth.
I do want to mention that i have stumbled upon 2 other topics that seem to describe a somewhat similar case, but without a specific answer. Both for Custom Auth
