ExtendedAttributes are being ignored in Update Events REST Endpoint

Hi everyone,

I am trying to find out how to update ExtendedAttributes for events via the Update Events REST Endpoint as documented here,


Which strangely uses a string instead of the RestExtendedAttributes used by REST endpoints like Create Group REST Endpoint


I have tried both approaches, including several others, just blindly trying to come up with something that would either produce an error, or change ExtendedAttributes  to anything else other than null.

Does anyone has any idea what format ExtendedAttributes  for Events is supposed to be, or it is just ignored by the Events REST endpoint regardless of what gets given in the call?

Thanks in advance,
