Client_ID: 250400000000000001

When I try this URL to get an access code: 'https://canvas.instructure.com/login/oauth2/auth?client_id=250400000000000001&response_type=code&red.../api/v1/courses url:POST|/api/v1/courses url:GET|/api/v1/users/self url:GET|/api/v1/accounts/self url:GET|/api/v1/assignments&state=sample_state'

I get the correct redirect, but returned with this URL: 'https://paramedicine101.bubbleapps.io/version-test/lti_launch?error=unauthorized_client&error_descri...

Can someone point me in the right direction?
