There seems to be an issue with less calc function

[yuxuan]

To reproduce the issue, check this https://github.com/yuxuan/less-plugin-functions-issue.

The less code:

@padding: 12px;

.cls {
  padding-right: calc(@padding - var(--width));
}

if compile with LessPluginFunctions, it would throw Cannot read property 'numerator' of undefined error. If without the plugin, it compiled successfully.

Please help.

It seems due to this commit less/less.js@1800743
