Use SalesForce Credentials for HTTP Request nodes

[laurens-novyx]

It looks like you might be having this problem:
(Which N8N version are you using?)

Refresh Token usage for Exact Online

Ah yes, this can be in fact the root of the problem. We already released an update for n8n where credentials are always saved to database after each execution and are always loaded from database before an execution. In a case where the credentials expire (like the 10 minutes window for the access token) and all workflows start at the same time, they will all load the same “outdated” credential and request a refresh token at the same time. I hope this solves the issues you are facing.

I am using the same SF credentials and after the update it works fine for me once again.
