Viem Version

2.33.2

Current Behavior

Looks like watchEvent internally validates wrong error and doesn't re-initiate the filter if it was uninstalled (latest code):

            // If a filter has been set and gets uninstalled, providers will throw an InvalidInput error.
            // Reinitialize the filter when this occurs
            if (filter && err instanceof InvalidInputRpcError)
              initialized = false
            emit.onError?.(err as Error)

I am getting InvalidRequestRpcError instead on the onError callback though:

URL: https://base-mainnet.g.alchemy.com/v2/{api_key}
Request body: {"method":"eth_getFilterChanges","params":[filter_id]}

Details: filter not found
Version: viem@2.33.2
InvalidRequestRpcError JSON is not a valid request object.

Expected Behavior

watchEvent should re-create a filter on the next poll if it was uninstalled

Steps To Reproduce

1. start listening to watch even
2. uninstall it
3. keep getting error onError callback
