Still `Error: invalid character '<' looking for beginning of value` even followed instructions from #47

what strange is, my browser can open it normally

Start with issue #47 and reproduce the reported command while comparing its response with the browser result shown in the screenshots. No source file or test is named, so first locate the CLI entry point handling the Vimeo request; done means the reported private-video case no longer returns the invalid-character error.
