I have integrated a Facebook OAuth login into my website. I have used the same script specified in the Facebook documentation, But am getting a blank screen for the popup. While inspecting the browser console, I could see the below error message. I have used the same script specified in the doc and replaced the APPID and Graph API versions. I have used v19.0 as the Graph API version.
ErrorUtils caught an error:
Minified invariant #21945;
Subsequent non-fatal errors won't be logged; see https://fburl.com/debugjs.
I have used the below code,
