-canOpenURL: failed URL: "fbauth2: /" - error: "(null)"

Question

I am using the latest version of Facebbok Sdk, i.e. 4.8.0, for sharing photos from my application. Everything works fine if the Facebook application is installed on my device, but it displays a warning

-canOpenURL: failed URL: "fbauth2: /" - error: "(null)"

if I uninstall the Facebook application and I can no longer share photos. I also set up my info.plist like this →

<key>LSApplicationQueriesSchemes</key>
    <array>
        <string>fbapi</string>
        <string>fb-messenger-api</string>
        <string>fbauth2</string>
        <string>fbshareextension</string>
    </array>

I also used various links, but nothing helped me. Thanx for any help in advance.
