Issues Creating Index and Using Search Tool with Fully Private AI Foundry Hub Setup

[AnjaneyalnDatla]

We are attempting to create an AI Foundry Hub and project in a fully private configuration, including all dependencies:

Private resources: Hub, Azure AI Services, Azure AI Search, Storage Account, Key Vault, App Insights, Container Registry

Outbound access: Restricted to Allow only approved outbound. ( same issues happens with allow internet outbound as well)

Guides followed:

Configure private link - AI Foundry
Secure Playground

(Repeated all setup steps multiple times as per documentation)

❗ Issue 1: Failing to Create Index via "Data + Indexes"
We are blocked when attempting to create an index using the "Data + Indexes" option in the project. The operation fails with the following error:
{
"Code": "data-capability.data-capability.FailedToInitializeCapabilitySession.start.UserErrorException",
"Category": "UserError",
"Message": "[REDACTED]",
"Details": [
{
"Name": "Reason",
"Value": "[REDACTED]"
},
{
"Name": "StackTrace",
"Value": " File "/opt/miniconda/envs/data-capability/lib/python3.9/site-packages/azureml/_restclient/clientbase.py", line 359, in _execute_func_internal\n response = func(*args, **kwargs)\n\n File "/opt/miniconda/envs/data-capability/lib/python3.9/site-packages/azureml/_restclient/operations/run_operations.py", line 506, in get_by_exp_id\n raise models.ErrorResponseException(self._deserialize, response)\n"
}
]
}
❗ Issue 2: AzureAISearch Tool Fails in Agent Prompt
In the Agents (preview) section, we are able to create an agent and add knowledge through the UI. This successfully creates an index using the AI Search tool.

However, when we attempt to query this knowledge base via the prompt in agents playground, we receive the following error: tool_server_error: Error: search_tool_server_error; Something went wrong when using the AzureAISearch tool.

Has anyone been able to get this setup work successfully? any pointer for us please

The documentation supports only the Chat Playground with the Add your data feature, not Agent Playground in AI Foundry hubs/projects. Is there a specific reason you are using Foundry hubs/projects and not the new Foundry resource type and the now GA Agent service?
