Unable to update asset value using API

Hi,
I am unable to update asset value using HTTP request. I am using the Post method - sets the asset value associated to the given robot key.
I have passed all the parameters correctly as required still getting error message - ‘actionParameters must not be null’.

Can anyone suggest what is going wrong? Also, is machine key to be passed in ‘robotKey’ parameter?

Thanks in adv!

Hi

Can you share your call api code?

Make sure pass in header:

X-UiPath-TenantName
X-UiPath-OrganizationUnitId (Asset folder)

and pass Asset ID in relative endpoint (/odata/Assets(38364))
