bug: confusing error message when you provide a single node as argument for a relationship of cardinality many

[wvandeun]

Component

Python SDK

Infrahub SDK version

1.1.0

Current Behavior

When you provide a single node for a relationship of cardinality many when creating a new a new node, the SDK correctly detects that this is an invalid scenario and raises an exception

ValueError: Unexpected format for pod found a <class 'infrahub_sdk.node.InfraPodInfrahubNodeSync'>, InfraPod (1810d2ce-5f36-5c88-32b5-c51e64ae0d8f) 

However the error message is not really clear.

Expected Behavior

Provide a clearer error message to indidcate that we were expecting a list of object since this is a cardinality many relationship.

Steps to Reproduce

• spin up infrahub
• load this schema

---
version: "1.0"
nodes:
  - name: Pod
    namespace: Infra
    attributes:
      - name: name
        kind: Text
        optional: false
        unique: true
  - name: IPPrefix
    namespace: Test
    include_in_menu: false
    inherit_from:
      - "BuiltinIPPrefix"
    description: "IPv4 or IPv6 network"
    icon: "mdi:ip-network"
    label: "IP Prefix"
    attributes:
      - name: network_name
        kind: Text
        description: "Name of the network"
      - name: gateway_address
        kind: IPHost
        description: "Gateway address in CIDR notation"
    relationships:
      - name: pod
        peer: InfraPod
        optional: true
        cardinality: many

• open a Python REPL and execute the following code

from infrahub_sdk import InfrahubClientSync, Config
client = InfrahubClientSync(config=config)
pod = client.create("InfraPod", name="pod")
pod.save()

prefix = client.create("TestIPPrefix", network_name="zzz", gateway_address_cidr="10.0.0.1/24", pod=pod)
prefix.save()
