Seems weird to include this kind of formatting in the message of an Error, but we probably don't have any other options, do we?

we could squish it in cause, but the intuition (and MDN doc) tells me that the message is for human readable errors and cause is for structured data / original errors in case of rethrowing.

Yeah, sounds reasonable. Still, the newlines freak me out 😄
Could we also include the whole response body somewhere in cause?

multiline error messages are quite common, we use those in several places already, also playwright and puppeteer do the same (and much worse, e.g. 10+ lines error messages, namely those about a missing browser executable). you can attach metadata to the error instance too, but its better to have a custom error class for that so its discoverable. we also use this approach (but we don't add any metadata there, just custom error prototypes).

Had to bump got to have sindresorhus/got#2327 , which caused the build to break... fixed by the tsconfig.json update. Happy to get feedback on that, it fixes the build, but might not be the best way around it.
Connected to https://github.com/apify/apify-proxy/issues/823.
On an internal proxy error (such as trying to access an invalid or unresolvable URL - e.g.
https://example.comundefined), the proxy returns a response with the error message.got-scrapingonly logs the length of the message, which is quite useless for most applications.
