babel-loader. exclude[0] must be a string/Function/RegExp

[anvlkv]

Hi, I'm trying to use thread-loader with babel-loader but I have this error:

".exclude[0] must be a string/Function/RegExp."
"Error: .exclude[0] must be a string/Function/RegExp.

I have an exclude option set on bable-loader, but even if i comment it out I have the error.

threadLoader.warmup(
    {
        // pool options, like passed to loader options
        // must match loader options to boot the correct pool
        name: 'babel-pool',
        poolRespawn: !isDev
    },
    [
        'babel-loader'
        // '@babel/preset-env',
