In fact, the file don't seem to exist. Tried to get them using wget from the traefik container directly and I get a 404 error. For other files, all was good. I do think the js file are build for production with tool like vite... or webpack.

@rtribotte No problem. The thing is: the files don't exist in fact. Those are part of build process but are not there , leading to 404 error with wrong type mime so. Note that filenames can change over each build.
