I'm reasonably sure that the fingerprint library comes with an example. Start with that and see if it works as expected.

Using OLED and WiFi only distracts from the issue at hand (for you and for us).

Next you can add WiFi/HTTP and get the combination of fingerprint and WiFi/HTTP working.
Next you can add OLED to the original fingerprint and get that combination working.
And lastly integrate it all.

With the given approach you can find out where problems are.
