CA is uninitialized and unable to sign certificates yet

Hi there,
I am setting up a HA vault (in production) consul on docker-compose (docker) consisting of 3 consul servers, 2 consul clients and 2 vault servers. I started with a self-signed certificate with most of the services working fine, and I am able to use the services to store and retrieve secrets. However, I often get the following messages when looking through the consul server logs:

consul.server2  | 2024-07-18T09:32:36.959Z [WARN]  agent.leaf-certs: handling error in Manager.Notify: error="rpc error making call: ACL not found" index=1

I generated the certificates using consul via consul tls create...... Can anyone let me know why I get this error? Thanks
