Sourcemaps uploaded but file size is always 125.0 B

[drowsy creek]

Hi, I have a React Native app that I'm trying to make sure sourcemaps are uploaded correctly to Sentry. I have tried both the automatic approach when building the app as well as the manual approach via sentry cli but none worked for me. I have verified that the sourcemaps are generated locally successfully and they contain valid data (about 42 MB in size). However, the uploaded sourcemaps on Sentry are always just 125.0 B in size and don't really contain any mappings. Could you please help? Thank you!

I'm using the following
"@sentry/react-native": "5.19.2"
"react-native": "0.70.14"
https://github.com/Kudo/react-native-v8 instead of hermes on Android
JSC on iOS

content of the uploaded sourcemap on Sentry (locally it is not empty)
{"version":3,"sources":[],"names":[],"mappings":"","x_facebook_sources":[],"debug_id":"f5be4981-5ef4-4176-b1c3-9ef8cbe845f7"}

because of this issue, all reported errors are not really readable for us

hey, I think this might be related to the fact that we cap individual artifact files at a max of 40MB.

Can you try reducing the size of your source maps and try sending them again?
