I have configured Oauth in a custom account in the splunk salesforce Add-On app. After configuring the account and saving the configuration it reaches out to salesforce. I login to salesforce and its states grant access. Once I click submit it comes back with an error
"Error occurred while trying to authenticate. Please try Again" in the app.
I am not sure what the issue is or if this is a need to configure something on the salesforce side.
How did you resolve this error? I am also facing same issue but before granting access.
@meekahHope you've figured out on how to ingest salesforce logs, but just in case please try to Turn Off "Require Proof Key for Code Exchange (PKCE) Extension for Supported Authorization Flows" checkbox in your Connected App's settings. It is located under the Scopes and Callback URLs (at least in old UI).
Trying also to figure out the problem. From salesforce topics they state that some permissions are missing on salesforce side. Will update shortly when solution is found
