ERR_INVALID_HTTP_RESPONSE

The server was expected to return an HTTP/1.x response, but did not. Rather than treat it as HTTP/0.9, this error is returned.

Chromium's description

The server was expected to return an HTTP/1.x response, but did not. Rather than treat it as HTTP/0.9, this error is returned.

Chrome shows it as net::ERR_INVALID_HTTP_RESPONSE, error -370. puppeteer and Playwright report the same name when a page fails to load in Chromium.

ERR_INVALID_HTTP_RESPONSE in the screenshot API

When the page itself fails to load with ERR_INVALID_HTTP_RESPONSE, the API answers 502 with the message The target website could not be loaded (ERR_INVALID_HTTP_RESPONSE). (target_unreachable). Not billed.

Only the page's own load can fail a render. An image, script or frame of the page that fails with a network error does not: the page is captured as the browser shows it without that resource.
