Hello
I am creating simple NodeJS app with express as server. The goal is authorize to ArcGIS online using CLIENT_ID and redirect to /authenticate page to get the access token .
Step 1: Authorization
const session = await arcgisRest.ArcGISIdentityManager.beginOAuth2({
clientId: clientId,
redirectUri: redirecturi,
pcke:true
});
The session has valid object "id":"MaLBpo4bA9dWkfDvuSN1SWYsGtlh0vkmvUUUPlQ5zU88","originalUrl":"http://localhost:3000/"
Step 2:
Now, when I use this authorization code to connect to ArcGIS online to get access, the token throws an error
I am encountering various errors, primarily related to invalid PKCE. The issue seems to be with the code_challenge_verifier. I used the appropriate cryptographic library to generate the code challenge, but it still fails with a 400 error.
I am looking for a good working sample.
