Topic: Cannot read property \\\'length\\\' of undefined

Ungr pro asked 6 years ago

Hello guys. Ive just downloaded https://git.mdbootstrap.com/mdb/jquery/jq-pro and I have problem whenever i try to use PRO scss. Btw: I use it only alone - without FREE scss - is that correct? ftb.scss 
$fa-font-path: '~font-awesome/fonts';
@import '~font-awesome/scss/font-awesome.scss';

@import '~bootstrap/scss/bootstrap';
@import '~mdbootstrap-pro/scss/mdb';
After running Symfony's Webpack Encore 
.\node_modules\.bin\encore.cmd production
error in ./src/AppBundle/Resources/public/scss/ftb.scss

sburina pro commented 6 years ago

I have exactly the same problem. Following th thread, hoping for a swift solution..

sburina pro answered 6 years ago

The culprit: /scss/pro/_accordion-extended.scss Line 3: 
background: linear-gradient(to 45deg, rgba(234, 21, 129, 0.6), rgba(10, 23, 187, 0.6) 100%);
My IDE says "Mismatched parameters". When I remove "to" from the first parameter, everytghing compiles just fine. So, the line that works for me is as follows: 
background: linear-gradient(45deg, rgba(234, 21, 129, 0.6), rgba(10, 23, 187, 0.6) 100%);

This works just flawlesly. Btw could you tell me how you were able to track the bug from the log? Or you encountered this one yourself earlier? I was literally trying to debug it the whole evening without a clue..

sburina pro commented 6 years ago

I wasn't. :) I simply remarked the @import lines in mdb.scss and tried building until I found it. Once the file was identified and linted, everything became clear. :)
