"unexpected error claiming task" when running self-hosted runner

Just got a response from CircleCI support to indicate that we are using a deprecated solution. Read the message below.

I will post later on how we replace this deprecated solution.

After reviewing the logs, it appears that your runner is attempting to access an endpoint that was deprecated on April 30, 2024 . We have extended the support for this endpoint until the end of August to assist you during this transition period.

To mitigate this issue and ensure continued seamless operation, we recommend migrating from the launch agent to Machine Runner 3.0 . Please follow the appropriate migration guide based on your operating system:

We have communicated the deprecation through various channels to keep our users informed:

Additionally, we will conduct a brownout from July 31st, 9 AM PST to August 1st, 9 AM PST (24 hours) to ensure all users are aware of the upcoming end-of-life.
