(wp-cli) Error 500

Hi, I’m trying to migrate one site through php script that runs:
exec(“cd ${directory} && /usr/local/bin/wp migrator start $token –email=$email –debug –allow-root”);

I attached console output:

Error 500

There is any way to debug this error ?
It doesn’t generate logs in my error.log file
