"Unspecified task queue kind" warnings in Temporal Server 1.23.0 (CLI version 0.12.0)

[tomwheeler]

When starting a local Temporal development server using Temporal CLI version 0.12.0, I observe multiple "Unspecified task queue kind" warnings in the terminal window. Although I experience this while using the CLI, I believe the underlying problem is in the server code, so I am reporting it here.

Expected Behavior

When starting the development server via the CLI, using the default options, I do not expect to see warnings or errors in the terminal window (except in case of user error, such as a port conflict on the machine).

Actual Behavior

After starting the development server via the CLI, I frequently see multiple warnings with the message "Unspecified task queue kind" in the terminal window where that server is running. Here is a complete copy of the terminal session in which I started the development server. There are 10 such warnings (amid three "error in prometheus reporter" warnings, about which I filed issue #5897 yesterday):

Steps to Reproduce the Problem

1. Install Temporal CLI version 0.12.0 (which is based on Temporal Server release 1.23.0). I did this via homebrew, although I doubt that the installation method is relevant
2. Run temporal server start-dev to start the development server
3. Run a few Workflows. The code I'm using isn't yet in a public repo, but I don't believe the problem is specific to this application. If you're unable to reproduce the problem, let me know and I will share the code and/or demonstrate it.

Specifications

• Version: Temporal CLI version 0.12.0
• Platform: M2 MacBook Pro, running MacOS 13.6.6

This is already fixed in server code #5661. It will be included in the next patch or minor release whenever comes first (1.23.2 or 1.24.0).
