I'm upgrading our environment from 2.16 to 2.17. I have node 16.x installed and the build process does run. However, users visiting the site get a 404 for bootstrap.css, and I see this in the build log for math4:
Proccessing themes/math4/bootstrap.scss
In themes/math4/bootstrap.scss:
Undefined variable.
╷
92 │ values: map-loop($theme-colors-rgb, rgba-css-var, "$key", "focus-ring")
│ ^^^^^^^^^^^^^^^^^
╵
node_modules/bootstrap/scss/_utilities.scss 92:24 @import
themes/math4/bootstrap.scss 43:9 root stylesheet
Not sure what I'm missing here?
Thanks,
Charles
