ERR_INVALID_ARG_TYPE

[jvolker]

I'm trying to use this module in Electron with Vue. The module works well outside this setup. But during development using the webpack dev server, as soon as I require the module I receive this error:

Uncaught TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined
    at validateString (internal/validators.js:107)

Thanks.

This happens because the environment variables pointing to the windows dir / sysroot are undefined using Vue CLI:

node-adodb/lib/engine.js

Line 15 in 166feff

const sysroot = process.env['systemroot'] || process.env['windir'];

Not sure if this happens in dev mode only.

I fixed this by hardcoding the path:
