Is your feature request related to a problem? Please describe.
Add Error hash to transaction status. Which can be used for custom error message throwing from solidity.

Describe the solution you'd like
const errorHash = parseInt(e.error?.data?.data ?? e.error?.data ?? e.data?.data ?? e.data)

I have raised a PR for this: #855

Why not just add the originalError as sent by ethers.js?
That would help others a lot, myself included.

The originalError will help this draft(#907) too.
