undefinedError: Cannot read property 'trim' of undefined

Just a error message text is totally useless. Please at least show the code you get the error with (and the more information never hurts - see for example https://github.com/necolas/issue-guidelines/blob/master/CONTRIBUTING.md#bug-reports.

Getting the same error. Looks like it has to do with args being undefined in lib/tinyargs.js

less-plugin-functions/lib/tinyargs.js

Line 53 in 86d8551

parse_: function(args) {

Hello, Im having the same issue, I'm doing the following:

I took the example code from the repository:

.function {
    .foo(@x) {
        return: @x * 2;
    }
}

div {
    width: foo(21em); // -> 42em
}

Then I run the following command (Im in windows using lessc 4.1.2):

lessc --functions test.less

Then i get this message: undefinedError: Cannot read properties of undefined (reading 'trim')

Is there any recommendation to avoid this?

Thanks a lot!
