panic: Int64() out of bound for Rebus

[hivefive-space]

Hello

I have compiled the package from main with last commit (PR #18) and I receive the following error (please see below).
The daemon successfully starts and works until prometheus makes the request.

Please fix it if possible.

I could not find how to see the version of current cosmos-exporter (not seen in --help, -V or -v or version)
Here is the md5 hash

I'm also impacted by a similar issue with the canto chain.
I've built the latest version from master (5f4936f), the error is:

Start command was:

cosmos-exporter \
--bech-prefix canto \
--denom canto \
--denom-coefficient 1000000000000000000 \
--node canto-grpc.polkachu.com:15590 \

@hivefive-space, just pull requested a fix, can you try it?
#31

Edit: merged to master, can you let us know if that solves the issue for you too?
