Relayer doesn't wait for tx confirmation

Summary of Bug

Whenever relayer signs a transaction it doesn't wait for confirmation

Version

0.5

Steps to Reproduce

Initially I got the error while creating channel between persistence chain and cosmos chain using following command:

hermes create channel cosmoshub-4 core-1 --port-a transfer --port-b transfer -o unordered

Following was the error I got:

failed during a transaction submission step to chain id cosmoshub-4 with underlying error: Failed Tx: no confirmation

Then after starting the relayer this error comes often:

Jul 07 11:02:35 relayer-mainnet-test hermes[411383]: Jul 07 11:02:35.500  INFO [core-1:transfer/channel-7 -> cosmoshub-4] prepending Destination client update @ height 1-1505507
Jul 07 11:02:40 relayer-mainnet-test hermes[411383]: Jul 07 11:02:40.420  INFO [core-1:transfer/channel-7 -> cosmoshub-4] assembled batch of 2 message(s)
Jul 07 11:02:54 relayer-mainnet-test hermes[411383]: Jul 07 11:02:54.136 ERROR failed with underlying error: Failed Tx: no confirmation
Jul 07 11:03:08 relayer-mainnet-test hermes[411383]: Jul 07 11:03:08.734  INFO [cosmoshub-4:transfer/channel-146 -> core-1] generate messages from batch with 2 events

But the transaction can be found on chain when the tx hash is queried. What I was able to gather from the error was that cosmos pools the transaction and commits it a bit later. Hermes doesn't wait for that long and throws this error.

Acceptance Criteria

Is there a way to increase the timeout for transactions relayed by the relayer?

Hi Rohit,

Thanks for opening an issue.

We have actually been working on this a lot recently (#1146).

Would you consider using a pre-release version of Hermes? Specifically https://github.com/informalsystems/ibc-rs/releases/tag/v0.6.0-rc2.

Is there a way to increase the timeout for transactions relayed by the relayer?

Yes. Version 0.6.0-rc2 has two benefits:

• you can adjust rpc_timeout = '10s' to higher values for your cosmoshub-4 configuration to increase the timeout
• the TxNoConfirmation error is more helpful

Thanks Adi,

Will update hermes to the latest version.

Closing this as may have been fixed in the meantime. The problem seems to overlap partially with #1124 which we're still working on.

Rohit, hope the issue has been resolved by updating to 0.6.0-rc2, let us know otherwise.
