Can you give us more information about this MIME?

I apologize for the wait.

.log files are associated with text/x-log if the file implements Express.Multer.File (express, nest.js file handler)

and text/plain if

file --mime-type -b test.log
# output will be text/plain and inode/x-empty if file is empty

or

import path from 'path';
import mime from 'mime-types';

const ext = path.extname('./test.log');
const mimetype = mime.lookup(ext);

console.log(ext, mimetype);
