Uploading the dist folder should do the trick. Sounds like it’s maybe a server configuration issue. Typically the server should serve the index.html by default.
The warning “Some chunks are larger than 500 kBs after minification” isn’t causing this. It is just a warning that performance might be impacted. For a native app, this doesn’t matter because all the files are being served directly from the phone. When deploying on a server, it can affect the user depending on their internet speed to download the chunks.
