[midPoint] Bulk Assignment of Roles to Users via JSON API Request

[Alexander Bruckner]

Hello everyone,


we are currently trying to assign one role to multiple users via a JSON API request. We've already managed to do this over XML with this request body:

<s:pipeline xmlns:s=http://midpoint.evolveum.com/xml/ns/public/model/scripting-3
          xmlns:c=http://midpoint.evolveum.com/xml/ns/public/common/common-3
          xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance
          xmlns:xsd=http://www.w3.org/2001/XMLSchema
xmlns:q=http://prism.evolveum.com/xml/ns/public/query-3>
<s:search >
    <s:type>c:UserType</s:type>
    <s:searchFilter>
       <q:inOid>
          <q:value>c38dc04a-e780-4475-ad51-f42dd054f622</q:value>
          <q:value>cd244459-81fe-4208-a51c-111cae039185</q:value>
          <q:value>12d665c0-7114-4b49-97ba-94c4cd154f8a</q:value>
       </q:inOid>
    </s:searchFilter>
</s:search>
<s:sequence>
<s:action>
        <s:type>assign</s:type>
        <s:parameter>
            <s:name>role</s:name>
            <c:value xsi:type="xsd:string">a6afcd50-5f33-4250-8b93-62cb72e1a39a</c:value>
        </s:parameter>
    </s:action>
    </s:sequence>
    </s:pipeline>

But similar approaches do not seem to work for JSON. We attempted the recommended method via heterogenous lists as outlined in https://docs.evolveum.com/midpoint/devel/design/xml-json-yaml-vs-xnode-vs-internal-data/heterogeneous-lists/:

{
    "@ns" : http://midpoint.evolveum.com/xml/ns/public/model/scripting/extension-3,
    "pipeline": [
        {
            "@element": "search",
            "type": "c:UserType",
            "searchFilter": {
                "inOid": {
                    "value": [
                        "c38dc04a-e780-4475-ad51-f42dd054f622",
                        "cd244459-81fe-4208-a51c-111cae039185",
                        "12d665c0-7114-4b49-97ba-94c4cd154f8a"
                    ]
                }
            }
        },
        {
            "@element": "sequence",
            "@value": [
                {
                    "@element": "action",
                    "type": "assign",
                    "parameter": {
                        "type": "role",
                        "value": "a6afcd50-5f33-4250-8b93-62cb72e1a39a"
                    }
                }
            ]
        }
    ]
}

But received the error message:

<message>Wrong input value for ExecuteScriptType: RawType: (raw): XNode(list:2 elements))</message>
    <details>java.lang.IllegalArgumentException: Wrong input value for ExecuteScriptType: RawType: (raw): XNode(list:2 elements))

It seems like Pipeline is not expecting a list of objects.
Is there some error in our current JSON or is there a different way of writing the query?

If anyone of you has some advice regarding this, it would be greatly appreciated!


Thank you and best regards,
Alexander Bruckner
