Panic: Arithmetic overflow on claiming tokens using AssetExchangeContract

[anjalisn4]

I am following the simple asset from samples for besu.After network setup and contract deployments, on running node app/AssetExchangeERC20.js, I am getting this error

'Error: Returned error: VM Exception while processing transaction: revert -- Reason given: Panic: Arithmetic overflow.\n'

Did you run the instructions in the right sequence? And did all commands prior to this claim command succeed?

Hi @anjalisn4, I'd suggest to not use app/AssetExchangeERC20.js for testing, instead I'd suggest to use besu-cli to test the asset exchange whose instructions are available in our documentation: https://labs.hyperledger.org/weaver-dlt-interoperability/docs/external/getting-started/guide

Closing this, as didn't receive any response, hence assuming it is resolved.
