unable to resolve type URL error when running tests

[akankshadhyani05]

Hi, I am running an appchain using the latest sdk version (0.50.8) and I am trying to run test but I am getting error in my code which I have posted below:
Error is originating from this code(here cctptypes is a dependency that i am importing in my repo):

msgs := []sdk.Msg{}

	msgs = append(msgs, &cctptypes.MsgAddRemoteTokenMessenger{
		From:     gw.fiatTfRoles.Owner.FormattedAddress(),
		DomainId: 0,
		Address:  tokenMessenger,
	})

The error is:
"unable to resolve type URL /cctp.MsgAddRemoteTokenMessenger"

I have pasted the code snippet of its tx.pb.go file :

proto.RegisterType((*MsgAddRemoteTokenMessenger)(nil), "cctp.MsgAddRemoteTokenMessenger")
proto.RegisterType((*MsgAddRemoteTokenMessengerResponse)(nil), "cctp.MsgAddRemoteTokenMessengerResponse")

where could the issue be?

I have added these lines in my app.go file:

app.BasicModuleManager = module.NewBasicManagerFromManager(
		app.mm,
		map[string]module.AppModuleBasic{
			genutiltypes.ModuleName: genutil.NewAppModuleBasic(genutiltypes.DefaultMessageValidator),
			govtypes.ModuleName: gov.NewAppModuleBasic(
				[]govclient.ProposalHandler{
					paramsclient.ProposalHandler,
				},
			),
			CCTPModuleName:         cctp.AppModuleBasic{}
		},
	)

	app.BasicModuleManager.RegisterLegacyAminoCodec(legacyAmino)
	app.BasicModuleManager.RegisterInterfaces(interfaceRegistry)
