As mentioned in the issue template, you can also provide a repository as repro.

require is defined in regular bun runtime

If the same code works on Node, then that's a bun issue. Please check and report a compatibility issue on Bun https://github.com/oven-sh/bun/issues

no that code doesn't in node which is expected, but bun allows both esm and cjs in the same file, so its really a vite issue
