Error on login when used in production environment

Hello, first thanks for this very handy library!

Everything is working fine on dev environment but when I build to production using webpack I am having a few issues with the gapi script.

The build works fine but this is throw in the console then I first load the page

cb=gapi.loaded_0:75 Uncaught TypeError: a is not a function
    at google-login.js:1
    at h.o0 (cb=gapi.loaded_0:83)
    at xs (cb=gapi.loaded_0:86)
    at Wq (cb=gapi.loaded_0:86)
    at _.C.uea (cb=gapi.loaded_0:85)
    at Ap (cb=gapi.loaded_0:79)
    at <anonymous>

The thing is, this is not happening all the time. Sometimes it works and sometimes not. I think its possible that the function that checks if the script is loaded is not very accurate.

Any ideas?

It looks like the error comes from when the gapi auth fails, the onFailure props is called but there is no default prop so the function is undefined.

@ayualdilasalma Try to provide a onFailure function to your GoogleLogin component.

After checking the doc, the onSuccess and onFailure are indeed REQUIRED props.
