Required Parameters

--device-id -d

Target Device Id.

--json -j

Json to replace existing twin with. Provide file path or raw json.

--module-id -m

Target Module Id.

Optional Parameters

The following parameters are optional, but depending on the context, one or more might become required for the command to execute successfully.

--auth-type

Indicates whether the operation should auto-derive a policy key or use the current Azure AD session.
