For development purposes, I had a especially configured Google Chrome shortcut that allowed us to circumvent the same origin policy. This would in turn set a cookie with the result of the query to that endpoint, Anyway, the configured used to be as follows.
C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-gpu --disable-features=SameSiteByDefaultCookies,CookiesWithoutSameSiteMustBeSecure --disable-web-security --user-data-dir="C:\Users\joao.pereira\Documents\cors_user_data_dir"
However, as of Chrome 91, according to the release notes, the SameSiteDefaultCookies and CookiesWithoutSameSiteMustBeSecure would be dropped come Chrome 94.
Mar 18, 2021: The flags #same-site-by-default-cookies and #cookies-without-same-site-must-be-secure have been removed from chrome://flags as of Chrome 91, as the behavior is now enabled by default. In Chrome 94, the command-line flag --disable-features=SameSiteByDefaultCookies,CookiesWithoutSameSiteMustBeSecure will be removed.
And that's where we're at as Chrome 94 has arrived. With these dropped, I am currently unable to access the intended resources. Unfortunately, downgrading the Chrome version isn't an option either since the computer is controled by the organization. Setting another browser with a similiar configuration would work so suggestions in that regard are also appreciated.
