Before you start please confirm the following.

• Yes, I've searched similar issues on GitHub.
• Yes, I've checked whether this issue is covered in the Portainer documentation or knowledge base.

Problem Description

I'm starting Portainer with --log-level=INFO and --log-mode=JSON on the CLI, but when the services start, if you follow in docker logs (or wherever you're pumping STDOUT) then not all messages are emitted as JSON.

Expected Behavior

Every message is emitted as JSON.

Actual Behavior

portainer | {"level":"info","private-key":"/data/chisel/private-key.pem","time":1735767710,"caller":"github.com/portainer/portainer-ee/api/chisel/service.go:201","message":"found Chisel private key file on disk"}
