Some cookies are misusing the recommended "sameSite" attribute

I just recently noticed the error referenced in the subject line popping up in my console window. The error I’m getting looks like this:

Cookie “CF_CLIENT_COM_SELECT184” will be soon rejected because it has the “sameSite” attribute set to “none” or an invalid value, without the “secure” attribute. To know more about the “sameSite“ attribute, read https://developer.mozilla.org/docs/Web/HTTP/Cookies debtor

I checked in multiple browsers to see if the same error was being generated and it’s identical across them all.

It hasn’t broken any of the features of my app, at least not yet. I’m not sure where I’d go to even correct such an error.

Support for same site cookies is coming soon, it’s not yet merged in. In the meantime you can rewrite cookies via your webserver. You can also ignore this warning for now
