invalid msg content creation for ForwardMsg in SwapMsg of ibc-denom-resolver

[taiki1frsh]

when to execute ForwardMsg, this error occurs.

Error: rpc error: code = Unknown desc = rpc error: code = Unknown desc = failed to execute message; message index: 0: dispatch: submessages: Error parsing into type packet_forward::msgs::ExecuteMsg: unknown variant `emergency_claimer`, expected one of `forward_msg`, `claim_failed_request_msg`, `update_config_msg`: execute wasm contract failed [CosmWasm/wasmd@v0.40.1/x/wasm/keeper/keeper.go:394] With gas wanted: '18446744073709551615' and gas used: '237871' : unknown request

In the unit test, we get this msg content in string

...
msg: {"emergency_claimer":"anyone","receiver":"osmo1xv9tklw7d82sezh9haa573wufgy59vmwe6xxe5",
 "port":"transfer","channel":"channel-0","timeout":{"secs":3600,"nanos":0},
 ...

This has to begin with "forward": {....}.
But, somehow it starts with the bold msg args. Not sure why
