How to pass "Collection type" Parameter from Client Code to Business Process.

Hi Community,

Any idea what went wrong on how i am passing "Collection type" Parameter from Client Code to Business Process.

Client Code:

Below is my payload and it seems fine:

{"schemaName":"UsrWEKAddFacRoute","parameterValues":[{"name":"RouteId","value":"3706a818-cab1-43b0-9a46-58115bb5026c"},{"name":"Facilities","value":[{"FacilityId":"449373f8-3091-4537-a79f-42645bdac2a9"},{"FacilityId":"6d06008f-71d0-4633-b5bb-a395e775a26f"}]}]}

Here is my Business Process input parameters:


However, I am getting this error
