the RUST_BACKTRACE didn't have any extra info but i looked at https://github.com/web-infra-dev/rspack-sources/blob/main/src/helpers.rs#L838C26-L842C43 and saw it was related to source mapping so i added
rsbuildFinal: config => {
config.output ||= {}
config.output.assetPrefix = './'
delete config.output.sourceMap
return config
},
and it worked. i like source maps but didn't strictly need them so this was fine. potentially we do some weird things in our repo, and it is open source and i can link it if interested
