IBC Contract Deployment Issue between Ethereum Nodes

[gokulsan]

Dear All,

We are attempting to create an IBC based interoperability system that can connect between an Ethereum node and Ethereum Rollups and Cosmos based Chains. We are using the IBC relayers and IBC relayers from Hyperledger Labs. As part of this project, we are trying to do transactions between an Ethereum node in HardHat and another Ethereum Proof of Authority Node. The transactions are getting reverted with the error between these nodes. On Hardhat node it says the IBC Client Not Found. On the PoA node, it says failed to get the client state. Please find the errors included below. Request your kind support in this issue.

Issue in the Hardhat Node
