bug: Coder treats all devcontainers as if they were managed by Coder #19345
Description
Is there an existing issue for this?

Current Behavior
Hello,
We recently started having issues with our workspaces after upgrading to 2.24.X. For some reason, Coder thinks that all the devcontainers in the machine are managed by Coder, even if they were not provisioned at all by it. This leads to the workspace reporting unhealthy and preventing the clients from connecting with it.
Is this a known issue in 2.24 ? Is there any workaround ?
Thanks!
