[BUG] setting capabilities to federatedKnowledgeSource causes ApiDefinitionCapabilitiesInvalid error

[meiaestro]

Type of Connector

Custom Connector

Name of Connector

Virtual Data Platform

Describe the bug

When changing the apiProperties.json as described in the enhanced-connector-sample to:

"capabilities": ["tabular", "federatedKnowledgeSource"]

I receive the following error during paconn update:

{
  "error": {
    "code": "ApiDefinitionCapabilitiesInvalid",
    "message": "The custom connector property 'Capabilities' is not a string array."
  }
}

I do not get an error when removing "federatedKnowledgeSource".

Less important, but I would be thankful for a hint: If "capabilities" is set to ["tabular"] and I run an update and a download afterwards, in some cases the "tabular" value has disappeared completely. I've not yet identified a reproducable setup.

Is this a security bug?

No, this is not a security bug

What is the severity of this bug?

Severity 2 - One or more important connector features are down

To Reproduce

add "federatedKnowledgeSource" to the capabilities of a working apiProperties.json and try to update the connector via paconn.

Expected behavior

Successful update with no "ApiDefinitionCapabilitiesInvalid" Error.

Environment summary

paconn v0.0.20
Windows 11
PSVersion 7.5.4
python 3.11.0
