Theme "VAADIN/themes/mytheme" compiled

There are a couple of problems here:

• I can't use the error message for much because there's no information about where in the source code the problem was found. At the very least a file name and a line number is required for the log message to be useful.

• If the problem is really of type SEVERE how come the compilation actually succeeds ?

in Our Server the Changes in my.scss-File from https://dev.vaadin.com/ticket/17373 leads to the Error above

[Vivek-Kalola]

open your 'my.scss' and make below changes,

**@import "../valo/valo.scss";
@import "custom.scss";

@mixin my {
@include valo;
@include custom;
}**

Make sure your parent theme is the first one, in given example 'VALO' and than right your custom created .scss files.

This helped me to resolve the error.
