packet-forward-middleware not working as expected

[devon-chain]

Summary of Bug

When I forward ibc transfer tx to osmosis via cosmoshub, if the amount is greater than the maximum value of int64, the estimated will fail, this problem exists in both mainnet and testnet

Before the v4.0.6 of packet-forward-middleware, if ibc transfer amount was greater than the maximum value of int64, the conversion would overflow, causing the code to panic, and tx would fail

Related issues:
gaia #2553
packet-forward-middleware #78

Version

gaia: v10.0.2(Latest)
gaia: v11.0.0(Pre-release)

Steps to Reproduce

Send ibc transfer tx to chainA(Any chain with which cosmoshub has created an ibc channel), receiver is cosmoshub, amount must be greater than maximum value of int64, and fill tx memo with forward data (for example, forward to osmosis/evmos/kava)

This issue should have been addressed in v4.0.6 of the packet forward middleware, it looks like Gaia is still using v4.0.5. I suspect that an upgrade to the patched version is all that is necessary to rectify the issue.

@devon-chain Thanks for opening the issue. I opened a PR to bump the PFM version #2677. Thanks @jtieri.
