I have setup a connected app and want to use the OAuth JWT. Based on my understanding of the salesforce documentation only preauthorized client can use this flow to get an access token.
I have enabled "admin approved users are pre-authorized" setting in my connected and enabled certain profiles under this. the certificate and other settings required for this flow has been set up as well.
I still get the following error while trying to get an access token using the JWT token.
{ error_description: "user hasn't approved this consumer" error:
"invalid_grant" }
the grant_type is set to "urn:ietf:params:oauth:grant-type:jwt-bearer"
and assertion: "base64url-encoded JWT token"
Appreciate any help to get this working!

Based from the salesforce documentation:
It means you have to authorize the application at least once.
https://login.salesforce.com/services/oauth2/authorize?client_id=[clientId]&redirect_uri=[redirectUri]&response_type=code
You don't need to work on the redirectUri.
