Firefox says:
Cookie “
session
” does not have a proper “SameSite
” attribute value. Soon, cookies without the “SameSite
” attribute or with an invalid value will be treated as “Lax
”. This means that the cookie will no longer be sent in third-party contexts. If your application depends on this cookie being available in such contexts, please add the “SameSite=None
“ attribute to it. To know more about the “SameSite
“ attribute, read https://developer.mozilla.org/docs/Web/HTTP/Headers/Set-Cookie/SameSite
This is probably an upstream bug in either
Flask-Session
oridentity
.
