Details

The source maps stopped working on Sentry. After discussing with their team, we identified that the issue was caused by an invalid source map generated by Rspack.

When testing the source map with source-map-explorer or other tools, the following error appeared:

'Your source map refers to generated column 53099 on line 39, but the source only contains 53098 columns on that line. Please verify that you are using the correct source map.'

Approximately 70% of the source map files we tested are working, while 30% have failed.
