Link To Reproduction

Not needed

Expected Behaviour

Would expect rollup to not throw any errors

Actual Behaviour

When starting development, rollup\dist\native.js throws a TypeError: undefined is not an object (evaluating 'report.getReport().header.osName')

This is because process.report.getReport is not implemented on Bun / Windows: oven-sh/bun#11992

An easy fix would be to change the line from

base: report.getReport().header.osName.startsWith('MINGW32_NT')

to

base: report.getReport().header?.osName.startsWith('MINGW32_NT')
