I want to attach these files as a zip archive:

And this is what I did:

emailext([
    attachLog: true, 
    subject: 'Hello World',
    recipientProviders: [developers(), requestor()],
    to: '$DEFAULT_RECIPIENTS',
    body: "hello world",
    compressLog: true,
    mimeType: 'text/html',
])

Unfortunately this is attaching the whole console.log (into a zip called build).

How can I fix this?
