0 syntax error, unexpected token "<", expecting end of file

This message I got when I tried to migrate:

CRITICAL 81.207.92.xxx error Uncaught Throwable of type ParseError thrown with message "syntax error, unexpected token "<", expecting end of file". Stack trace: #0 [ROOT]/libraries/vendor/composer/ClassLoader.php(427): Composer\Autoload{closure}()

Nothing seems to have been migrated.
