FIX: Error while creating Hermes relayer client between Earth and Mars chains (in IBC Tutorial)

[Srutip04]

Title: Error while creating Hermes relayer client between Earth and Mars chains

Description:

I am trying to configure a Hermes relayer between two chains, Earth and Mars, using the Ignite CLI. During the configuration process, I encountered an error while attempting to create a client. Below are the details of the issue:

Steps to Reproduce:

1. Run the following command to configure the Hermes relayer:

   ignite relayer hermes configure "earth" "http://localhost:26657" "http://localhost:9090" "mars" "http://localhost:26659" "http://localhost:9092" --chain-a-faucet "http://0.0.0.0:4500" --chain-b-faucet "http://0.0.0.0:4501" --chain-a-port-id "blog" --chain-b-port-id "blog" --channel-version "blog-1"

2. Confirm the reuse of the existing configuration file.

3. Observe the following error message after the configuration:

   ✘ Error while running command /tmp/hermes3270493899 --config=/root/.ignite/relayer/hermes/earth_mars --json create client --host-chain=earth --reference-chain=mars: exit status 1
   

Expected Behavior:

I expected the command to successfully create a client between the Earth and Mars chains.

Actual Behavior:

The command fails with an error indicating that it exited with status 1.

Environment:

Additional Information:

• I have already checked the following:
  • Both chains (Earth and Mars) are running and accessible.
  • The RPC and gRPC addresses provided in the command are correct.
  • I have sufficient balance in both relayer wallets.

I have the same problem. These are my logs:

@Srutip04 We can fix it by this:

Hermes earth <-> mars config already exist at /Users/levi/.ignite/relayer/hermes/earth_mars. Do you want to reuse this config file: N

Now it is working:

btw, I don't know the core reason of it, maybe someone could provide some ideas?

Oh no, when I delete the cache rm -rf ~/.ignite/relayer and retry, it is fail:

@chen4903
In your case, you need to update your configuration file /Users/levi/.ignite/relayer/hermes/earth_mars contents as follows:

Replace trust_threshold = {denominator = '0', numerator = '0'} with trust_threshold = {denominator = '3', numerator = '2'} in all occurences.

After this run the command:

ignite relayer hermes configure "earth" "http://localhost:26657" "http://localhost:9090" "mars" "http://localhost:26659" "http://localhost:9092" --chain-a-faucet "http://0.0.0.0:4500" --chain-b-faucet "http://0.0.0.0:4501" --chain-a-port-id "blog" --chain-b-port-id "blog" --channel-version "blog-1"

(I have flattened it as compared to what was mentioned in the doc)

You will get the error that @Srutip04 has mentioned.

Please note that you also need to update the earth.yml file to:

version: 1
build:
  proto:
    path: proto
    third_party_paths:
    - third_party/proto
    - proto_vendor
accounts:

  coins:

    rpc:
      laddr: :26657
      pprof_laddr: :6060
  home: $HOME/.earth

This is wrongly mentioned in the doc.

I agree with @Srutip04 that this error exists even after fixing all the bugs, as I mentioned above i.e.,

• Both chains (Earth and Mars) are running and accessible.
• The RPC and gRPC addresses provided in the command are correct.
• I have sufficient balance in both relayer wallets.

Hi @chen4903 and @Srutip04 ,

Here is a solution to the above problem that worked for me. Thanks to a member of the Hermes team (@ljoss17) for helping me out with this. The problem is that Ignite does not generate the correct config file for Hermes.

You can update the config file as follows:

[global]
log_level = 'error'

[mode]
[mode.clients]
enabled = true
refresh = true
misbehaviour = true

[mode.connections]
enabled = true

[mode.channels]
enabled = true

[mode.packets]
enabled = true
clear_interval = 100
clear_on_start = true
tx_confirmation = true
auto_register_counterparty_payee = false

[rest]
enabled = false
host = '127.0.0.1'
port = 3000

[telemetry]
enabled = false
host = '127.0.0.1'
port = 3001

[[chains]]
id = 'earth'
type = 'CosmosSdk'
ccv_consumer_chain = false
rpc_addr = 'http://localhost:26657'
grpc_addr = 'http://localhost:9090'
event_source = {batch_delay = '500ms', mode = 'push', url = 'ws://localhost:26657/websocket'}
rpc_timeout = '10s'
trusted_node = true
account_prefix = 'cosmos'
key_name = 'wallet'
address_type = {derivation = 'cosmos'}
key_store_type = 'Test'
store_prefix = 'ibc'
default_gas = 1000000
max_gas = 10000000
gas_price = {denom = 'stake', price = 0.001}
gas_multiplier = 1.2
max_msg_num = 30
max_tx_size = 2097152
clock_drift = '5s'
max_block_time = '30s'
trusting_period = '14days'
trust_threshold = {denominator = '3', numerator = '2'}
memo_prefix = ''
sequential_batch_tx = false

[[chains]]
id = 'mars'
type = 'CosmosSdk'
ccv_consumer_chain = false
rpc_addr = 'http://localhost:26659'
grpc_addr = 'http://localhost:9092'
event_source = {batch_delay = '500ms', mode = 'push', url = 'ws://localhost:26659/websocket'}
rpc_timeout = '10s'
trusted_node = true
account_prefix = 'cosmos'
key_name = 'wallet'
address_type = {derivation = 'cosmos'}
key_store_type = 'Test'
store_prefix = 'ibc'
default_gas = 1000000
max_gas = 10000000
gas_price = {denom = 'stake', price = 0.001}
gas_multiplier = 1.2
max_msg_num = 30
max_tx_size = 2097152
clock_drift = '5s'
max_block_time = '30s'
trusting_period = '14days'
trust_threshold = {denominator = '3', numerator = '2'}
memo_prefix = ''
sequential_batch_tx = false

Then run:

ignite relayer hermes configure \
"earth" "http://localhost:26657/" "http://localhost:9090/" \
"mars" "http://localhost:26659/" "http://localhost:9092/" \      
--chain-a-faucet "http://0.0.0.0:4500/" \
--chain-b-faucet "http://0.0.0.0:4501/" \
--chain-a-port-id "transfer" \
--chain-b-port-id "transfer"

followed by:

ignite relayer hermes start "earth" "mars"

Now the command works:

planetd tx blog send-ibc-post transfer channel-1 "Hello" "Hello Mars, I'm Alice from Earth" --from alice --chain-id earth --home ~/.earth

Please update the port as transfer and the channel as the correct one based on the one generated for you.

@chen4903 I think it is created in this path that you mentioned in an earlier comment:
/Users/levi/.ignite/relayer/hermes/earth_mars

[chen4903]

Hi @stanlysamuel . I follow your advice, but I meet a new error:

$ ignite relayer hermes configure "earth" "http://localhost:26657" "http://localhost:9090" "mars" "http://localhost:26659" "http://localhost:9092" --chain-a-faucet "http://0.0.0.0:4500" --chain-b-faucet "http://0.0.0.0:4501" --chain-a-port-id "blog" --chain-b-port-id "blog" --channel-version "blog-1"

btw, I think manually modifying the Ignite configuration file is not the ultimate solution.
