Chrome DevTools Protocol: `Network.setCookie({ sameSite: 'None' })` fails, why?

Question

I'm having an issue where the Chrome DevTools Protocol returns { success: false } when sending a Network.setCookie request with sameSite set to "None".

What could the issue be? "Lax" and "Strict" appear to work fine.

Answer 1

sameSite can only be set to "None" on a secure cookie. Try passing { sameSite: "None", secure: true }.
