When I try and add new entities to a dataflow using the salesforce object connector I get the following error in Google Chrome:


Third party cookies are being blocked. Please enable third party cookies and try signing in again


I have allowed all thrird partr cookies in the chrome browser settings. If I use any other brower I don't get this error and I am able to add entities. 


Any help would be appricated.

Ok so I found the solution to this.


This is the chrome console error:


A cookie associated with a cross-site resource at was set without the `SameSite` attribute. It has been blocked, as Chrome now only delivers cookies with cross-site requests if they are set with `SameSite=None` and `Secure`. You can review cookies in developer tools under Application>Storage>Cookies and see more details at and



I therefore went into chrome://flags/ and disabled the same sites by default setting. This is the only way I could get ti to work. Any other ideas are welcome. 

SameSite by default cookies

Treat cookies that don't specify a SameSite attribute as if they were SameSite=Lax. Sites must specify SameSite=None in order to enable third-party usage. – Mac, Windows, Linux, Chrome OS, Android
