How to reference an exiting node by IP using iApp REST

Hi guys,

I'm using REST API to create a new Virtual Server (). It works and I'm able to create one if I use a name reference to an existing node, e.g.:

{
"name":"pool__members","columnNames":["addr","port","connection_limit"],"rows":[
    {"row":["/Common/Node_Debian_1","80","0"]}]
}

However, I'm struggling to do the same using an IP of a node in case the node already exists (if the node did not exist before my REST call, a new one is created).

e.g. If I use this:

{
"name":"pool__members","columnNames":["addr","port","connection_limit"],"rows":[{"row":["/Common/172.19.81.210","80","0"]}]
}

I get this:

{
    "code": 400,
    "message": "0107003a:3: Pool member node (/Common/172.19.81.201) and existing node (/Common/Node_Debian_1) cannot use the same IP Address (172.19.81.201).",
    "errorStack": []
}

I would prefer to not do the workaround in my code - I would prefer the F5 simply takes the IP and either use an existing node, or create a new one - exactly the same way as the GUI does if creating a service from template: the GUI simply takes the IP and if an existing node exists, it will be used, if not, new will be created.

Any advice, please?

Running version 11.5.4.

Thank you.
