Go Relayer Issue

[torvald2]

I have issue with IBC and Go Relayer

When I trying send IBC Package got error "module does not own channel capability” in my observer module.
Capabilities have to store on path capabilities/ports/transfer/channels/channel-0
But when I created connection there no OnChanOpenInit call in my module

My Go replayer steps
rly chains add -f ./test_config/subnode_go_relayer.json
rly chains add -f ./test_config/government_go_ralayer.json
rly keys add government_go_ralayer test
rly keys add subnode_go_relayer test
rly paths new subnode government observer-path
rly transact clients observer-path
rly transact connection observer-path
rly transact channel observer-path
rly start observer-path

It’s creates channel-0 and port id transfer

Command subnetwork-noded query ibc channel channels --chain-id subnode --home ~/.subnode
Shows

channels:

• channel_id: channel-0
  connection_hops:
  • connection-0
    counterparty:
    channel_id: channel-0
    port_id: transfer
    ordering: ORDER_UNORDERED
    port_id: transfer
    state: STATE_OPEN
    upgrade_sequence: "0"
    version: ics20-1
    height:
    revision_height: "3746"
    revision_number: “0"

Channel and port is exists but there no capability for my module
It’s makes me crazy Help please ****

@torvald2 Hey! Was just forwarded this message from someone else

When you are building an IBC module, you need to claim the capability in your keeper. An example is like so

func (k Keeper) BindPort(ctx sdk.Context, portID string) error {
	capability := k.portKeeper.BindPort(ctx, portID)
	return k.ClaimCapability(ctx, capability, host.PortPath(portID))
}

This uses the github.com/cosmos/ibc-go/modules/capability module for v50, or cosmos-sdk/x/capability in < v47

A good example is in the ibc-go repo with the transfer keeper
