I'm trying to assign the value of column AssignedTo to multiple people, using data being read from another list with the same. I currently have this working with Create Item action, which requires hard-coding the Site / List name, and am trying to transition to using a generic HTTP request action to get around this. For all other fields this works fine, but when I try to set AssignedTo, I just can't find the right structure, or any way to inspect the Create Item POST body so that I can compare.
For the Create Item action, I construct an array into a variable such as:
[
{"Claims": "i:0#.f|membership|me@company.com.au"},
{"Claims": "i:0#.f|membership|other@company.com.au"}
]
And that goes into the AssignedTo field in Create Item form, and it just works.
Now I set my new composed body for HTTP request to e.g.
{
"Title": "@{variables('DocumentPath')}:@{items('Each_Stage')['RunOrder']}",
"AssignedTo": @{variables('Claims')}
}
using the exact same array, and the HTTP POST returns: Value cannot be null. Parameter name: entitySet
I believe that for multi-fields in general you need to wrap this into an object such as:
"AssignedTo": {"results": @{variables('Claims')}}
So I've tried that but that just gives a different error A node of type 'StartObject' was read from the JSON reader when trying to read the contents of an entity set reference navigation link; however, a 'StartArray' node was expected. I take that to mean it wants an array directly rather than this "results" object.
I've also tried both combinations but with the key AssignedToId instead of AssignedTo.
- Array:
'StartObject' node was found ... A 'PrimitiveValue' node was expected. - Object {"results": .. }:
'StartObject' node was found ... A 'StartArray' node was expected.
What am I missing here? I really want to avoid doing additional lookups of user data if it can be avoided, and clearly the "Claims" data should be authoritative and usable as it is, I just can't find the right way to express it in this request.
