Source Maps and simulated domains

[darrinm]

I am using a custom CefResourceManager::Provider to map subdomains to local directories. This works great except it seems that Chromium doesn't use the resource manager when it retrieves source maps so I get errors and no source maps .

Code: Select all

DevTools failed to load SourceMap: Could not load content for https://manager.ua.app/static/js/bundle.js.map: Connection error: net::ERR_NAME_NOT_RESOLVED
DevTools failed to load SourceMap: Could not load content for https://manager.ua.app/static/js/1.chunk.js.map: Connection error: net::ERR_NAME_NOT_RESOLVED


Is there away to intercept Chromium's source map requests like other browser requests?

Thanks much!

What OS and CEF version? Do you get CefResourceRequestHandler callbacks or those resources?

[darrinm]

Mac OS 10.15.6 (19G2021), CEF 85.3.11. No I don't see CefResourceRequestHandler, e.g. OnBeforeResourceLoad, callbacks for those resources.

OK, thanks for checking. Please add a bug in the issue tracker.

Thanks, will do. A point of interest, source map requests do appear to be special to Chrome (not referring to CEF here). For example, they are not reflected in the DevTools Network panel.

Was an issue ever logged on this? I'd like to monitor it's progress, as I recently stumbled across this as well.

Chromium still has some bugs related to source maps
