SASS script not working for page urls

Hi community,  the mendix sass gulp script ( is not working properly, if your application uses page urls for direct navigation.  It seems like, the root folder is not resolved correctly and browsersync is looking for the css-files in "localhost:3000/p/page" instead of "localhost:3000/".   Here the error messages from the browser console: GET http://localhost:3000/p/styles/css/lib/lib.css?636802148256840095&browsersync=1544614508135 net::ERR_ABORTED 404 (Not Found) GET http://localhost:3000/p/styles/css/custom/custom.css?636802148256840095&browsersync=1544614508143 net::ERR_ABORTED 404 (Not Found)   Has somebody else encountered this error and has a fix for if? Thanks in advance,  Alexander

Hi Alexander,

If you are working with Mendix 7, some things might have changed. I catalogued a few minor issues over the past months and tried to add them to the troubleshooting section of ux-theming.

Please have a look at this link: and see if you can fix it. I think you will have to adjust the settings json in your theme.

I will add the troubleshooting section to the docs at a later stage as well.


Hi Alexander,

I'm not having the same issue. Do you have the latest version of the Gulp file and browsersync?
