Describe the problem/error/question
User can not add salesforce sandbox credentials to n8n if the sandbox is using a developer license. You can only add partial copy sandbox’s to credentials.
What is the error message (if any)?
The OAuth URL is wrong. IF you select “Sandbox” for Environment Type. The URL on the OAuth pop up shows “login.salesforce.com” & this is wrong!
It should be https://test.salesforce.com.
