@jxom why did you close the issue? How can I fix it by myself? I think it’s library bug. It does not handle errors properly

Hard to tell what's going on without a minimal reproducible example. Most likely could be a RPC provider that responds with a malformed response/response that isn't shaped properly.

@jxom I've invited you to the example repo https://github.com/aarifkhamdi/viem-reading-null

[aarifkhamdi]

I added minimal reproducible example. Reopen issue please
