🤔 Expected behavior

The error message should be like No instance with ID 'dummyinstanceid' found.

☕ Steps to reproduce

What Durable Functions patterns are you using, if any?

Durable Functions HTTP starter

Any minimal reproducer we can use?

The following code reproduces this bug:

import azure.durable_functions as df
import azure.functions as func


async def main(req: func.HttpRequest, starter: str) -> func.HttpResponse:
    client = df.DurableOrchestrationClient(starter)

    await client.terminate("dummyinstanceid", "foo")

    return func.HttpResponse(status_code=200)

Are you running this locally or on Azure?

I am running this locally with following versions.

azure-functions==1.13.3
azure-functions-durable==1.2.2

⚡If deployed to Azure

We have access to a lot of telemetry that can help with investigations. Please provide as much of the following information as you can to help us investigate!

• Timeframe issue observed:
• Function App name:
• Function name(s):
• Azure region:
• Orchestration instance ID(s):
• Azure storage account name:

If you don't want to share your Function App or storage account name GitHub, please at least share the orchestration instance ID. Otherwise it's extremely difficult to look up information.
