BTW, aws-kms-provider has been rewrite into @cloud-cryptographic-wallet/web3-provider-adapter and @cloud-cryptographic-wallet/aws-kms-signer.
I recommend switching to this libraries if possible.

I'm working on resolving the GitHub Actions error.
It will be a while before I can merge the pull requests and publish the library.
