Having issues with OAuth

I am having issues with the OAuth. It says client_Id not found and when I run it in sandbox mode, the browser just shows a white screen. Attaching both the links here.

The issue you’re experiencing might be due to a typo in your authorization URL. The URL parameters should be separated by an “&” symbol. In your URL, it seems like there’s no “&” symbol between your client_id and scope parameters.

The corrected URL should look like this:

https://connect.squareupsandbox.com/oauth2/authorize?client_id=sandbox-sq0idb-FTtINL_p0onasFcRf3EC7w&scope=MERCHANT_PROFILE_READ%20PAYMENTS_READ&session=false

Please try using this corrected URL and see if the issue persists.
