This is happening for me whenever there’s any error in the pipeline, such as a posthtml error; Parcel tries to report the error, but there’s an error in the error reporting function itself.

https://github.com/parcel-bundler/parcel/blob/96119be782d9d551f73b77e06ab25067c7073344/packages/core/parcel-bundler/src/Pipeline.js#L30

This is making debugging issues a major pain; I’m having to manually add console.error(err) before the erroring line in Pipeline.js order to get a sense of what the error actually is.
