Example in README does not work

[gustiando]

Hi!

Thank you so much for creating this wonderful tool :)

I tried to execute the screenshot example, but unfortunately got an error when running the last line: File.write "screenshot.png", Base64.decode64(response["data"])

Error:
Encoding::UndefinedConversionError: "\x89" from ASCII-8BIT to UTF-8

Would you happen to know what's going on?

Thanks!

The file needs to be opened in binary mode. This is the equivalent and works:

File.open('screenshot.png', 'wb') { |f| f.write(Base64.decode64(response["data"])) }
