PHP error log 'Auth0\\SDK\\JWTVerifier not found

UPDATE:

I removed auth0-php: 4.0 and installed the following:

“require”: {
“firebase/php-jwt”: “^4.0”,
“bramus/router”: “dev-master”,
“auth0/auth0-php”: “~5.0”
}

This still DOES NOT resolve the issue.

My php still errors out when going to create the new JWTVerifier. It says it cannot find the class.

I noticed that composer created a vendor directory and that there is a bunch of library files in there. Any ideas why this isn’t working???
