[14.2.0-rc] Block Grid layout stylesheet not using correct URL

[rickbutterfield]

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

14.2.0-rc

Bug summary

When configuring a layout stylesheet against a Block Grid, the URL it is trying to be loaded from includes the backoffice path as part of the URL

Specifics

Screenshot of the network requests failing, going to the incorrect URL

Screenshot of the config returned from /umbraco/management/api/v1/data-type with the correct stylesheet URLs

I think the culprit is this part of block-grid-manager.context.ts

if (layoutStylesheet) {
    // Cause we await initAppUrl in setting the _editorConfiguration, we can trust the appUrl begin here.
    return this.#appUrl! + removeInitialSlashFromPath(transformServerPathToClientPath(layoutStylesheet));
}

When running the Backoffice project locally, appUrl will always resolve to http://localhost:5173, whereas when running within the context of a C# project, appUrl will resolve to the backoffice path.

A few lines down (L60-62) show where #appUrl is populated, and includes getBackofficePath():

this.#initAppUrl = this.getContext(UMB_APP_CONTEXT).then((appContext) => {
    this.#appUrl = appContext.getServerUrl() + appContext.getBackofficePath();
});

Steps to reproduce

• Blank v14.2.0-rc installation
• Create a test CSS file inside /wwwroot
• Configure a Block Grid datatype to have a layout stylesheet pointing to the above CSS file
• Check the browser console

Expected result / actual result

Expected result:
If a stylesheet is configured from /wwwroot/css/test.css, the loaded file should be seen as /css/test.css in the Network tab of dev tool

Actual result:
Stylesheet tries to be loaded from /umbracocss/test.css

Hi there @rickbutterfield!

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

• We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
• If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
• We'll replicate the issue to ensure that the problem is as described.
• We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.

Thanks, from your friendly Umbraco GitHub bot 🤖 🙂

Hey @nielslyngsoe - this still appears to be an issue in 14.3.1. The layout stylesheets still include the backofficeUrl of /umbraco in the path.

Would you like me to open a new issue?
