You have two possibilities here.

First is the issue is on your import, most likely it is the one causing the error, change your import to the code below OR

import { FingerprintAIO } from '@ionic-native/fingerprint-aio/ngx';"

It's either you have not imported the plugin on your app.module.ts

i think the problem came from your import , try this :

import { FingerprintAIO } from '@ionic-native/fingerprint-aio/ngx';
