Compiling JS failed: 7:1:invalid expression (possible JSX: pass -parse-jsx to parse) about repack

I checked the bundle file inside my app's file sandbox. Turns out if the bundle was not correctly fetched, the error message will be write into the bundle file.

hi @ra1nj,

have you checked what gets downloaded? This sort of error can happen when the resource isn't available - we don't check if the file looks like proper bundle before evaluating it (although we could do that to differentiate this case better 🤔).

Try manually downloading the bundle using the config from your logs to verify the correct file gets downloaded

hi @jbroma , thank you for your answer , it seems like it's the network problem, i changed to serve my bundle with a local express server, and it works like a charm 🥳.

@ra1nj feel free to make a PR that could make this error to easier to debug for others. I'm currently busy with other work and don't have capacity for that
