Customizer doesn't report Less compile errors (but does report syntax errors)

[tomillo]

I'm customizing the framework with my customs config.json, but when y click to the button "Compile and Download" it appears an alert with the url of my configuration and the download doesn't start. Is my problem or is it a bug?

Are you using Firefox by chance? See #15016.

[tomillo]

Nope, i'm using Chrome

[cvrebert]

Can you post a link to the Gist of the configuration that you're using?

The Chrome inspector says this "Uncaught Error: error evaluating function darken: undefined is not a function"

[cvrebert]

Your customized values make use of a nonexistent @font-size-base-bold variable.

[tomillo]

Thanks cvrebert. I fix that, but now the problem are the darken functions..

Well, it looks like we're not properly displaying the undefined variable error, so that's a bug in and of itself.

[tomillo]

I'm sory, i don't understand you... What do you suggest?

Hi!
I have the same problem since yesterday. I'm new to Bootstrap and I almost went crazy thinking I was doing something wrong. I tried with "all" browsers with old and new versions and nothing! What can we do?

[cvrebert]

@marfilag Try it again now. You should at least get an error message this time (unless it's the mysterious Firefox bug).

[cvrebert]

@tomillo Your subsequent problem is due to setting @btn-danger-border (and similar) to none instead of a color.
Less doesn't communicate the error very well, but the summary is that those variables must be colors, since they're used in color calculations elsewhere (in particular, they are used in some darken() invocations).

[marfilag]

Oh yeah, I could already download it from Firefox ... I love you guys, thanks!

Note: I also had to correct a mistake: I did not understand very well the error message, but when I made some changes was solved.

Thankyou @marfilag. Now i can download!
