propertiesV2list Failing With 404

Trying to use the IoT API, I can't get propertiesV2list to return the properties list.
It always returns:

{
    "id": "nB0XnalR",
    "code": "not_found",
    "status": 404,
    "detail": "thing not found: sql: no rows in result set"
}

I'm calling this, with no further args:

https://api2.arduino.cc/iot/v2/things/bb4bc077-398b-41d3-af33-4fc87ca9e868/properties

The Thing ID is known-good, and properties do exist, because this (propertiesV2Show) returns the expected result set without error (it's exactly the same as above, but with "/<variable's GUID>" added to the end):

https://api2.arduino.cc/iot/v2/things/bb4bc077-398b-41d3-af33-4fc87ca9e868/properties/cebc15fa-77a0-409c-944b-a4a8d3d20a74

Anyone know what I'm missing here?

Hi! This error is returned when thing id is not present.
Second call works because you have specified the correct property id, but thing id configured is not associated to the property id in url.
Please verify thing id.

For example, you can list all things associated to your account with call:

GET {{host}}/iot/v2/things?show_properties=true
Authorization: Bearer {{jwttoken}}

Thanks!

Thanks - that was the problem. I was using the ID on the Thing detail page's Setup tab, but that's not the Thing's ID - it's the ID of the Device shown above it. The Thing ID is on the Metadata tab.
