    your app is currently set to production in google developer console.

    enter image description here

    This means that all of the redirect uris you try to add to your project. Must be HTTPS and not HTTP you can also not use localhost

    As you are trying to use you need to change it so that it is note that the first one was http:// and not https://

    The error is coming because your application itself is trying to send a redirect uri of http and not https. You need to fix your application so that it is using https.
