Unknown protocol method

No registered Engine Protocol route handles the requested method, or a service cannot handle a method routed to it. The call fails without executing that method.

#Common causes

• A typo or a method name from a different engine version.
• A service's method catalog and dispatcher disagree.

#Fixes

• Call rpc.discover and use a method listed by the running host; apply the spelling suggestion when appropriate.

• Use the supported MCP tools such as ara_apply and ara_inspect, or correct a service's registration and dispatcher if they disagree.
