wiredep with exclude sometimes returns undefiend

[zivkaziv]

Hey all,

I'm facing really strange issue in our CI\CD.
Sometimes our build failed due to

Invalid glob argument: undefined

After investigating where is this undefined coming from, I've found that
const wiredep = require('wiredep');
const js = wiredep({exclude:[/jquery/, /font-awesome/]).js;
So now the js sometimes returns undefined.

Without the exclude options it works.

Any idea what I'm doing wrong?
Please help...

Thanks
Z
