403 error when trying to authenticate with bearer token

I’m trying to integrate a react native app with erpnext.

I’m using oauth2 and have a custom uri scheme to handle links in react native.

I’m getting the code and the access token successfully but when I make a request using the format Bearer ${accesstoken}

I get a 403 error. Is there any way to debug this?

share full request

it is Authorization: Bearer {access_token}

it is not Bearer: {access_token}
