Facebook plugin login error

I have tried installing the platform browser by using the following command – ionic cordova platform add browser but doesnt seem to work. Is there anything i am missing here. I heard ionic serve wouldnt work in this case since it is not a native emulator. Any workarounds_ ?

So a few things, we don’t support the cordova browser platform. In fact, many plugins do not support it, as it was never meant to be a full deployment target, but for testing.

So what you’re seeing is to be expected.
As for what to do…I would suggest trying the non-cordova plugin approach for auth.
