JS 'agents.listRunSteps' method raises the 'Unknown run step type: tool_calls' if Azure Foundry Agent with Azure function are used

Hello,

  1. I used the following example to create an Azure Foundry Agent with an Azure Function:
    GitHub - Azure-Samples/azure-functions-ai-services-agent-python: Sample to show using Azure Functions to run action functions from Azure AI Services
  2. I asked the agent a question that uses the function: “What is the weather in NY?”
  3. I then used the listRunSteps method to retrieve run steps:

try {
    let steps = await client.agents.listRunSteps(threadId, run.id)
    console.dir(steps)
} catch (error: any) {
    console.log('step error')
    console.dir(error)
}

I received the following exception:

Error: Unknown run step type: tool_calls

Note that the Python version of this API works correctly:
list_run_steps

Also, if the run does not use a function, this exception does not occur.
