Describe the bug
When quering /cosmos/tx/v1beta1/txs/block/ with block with no transaction (202296839 for example), i get error:

{
    "code": 3,
    "message": "out of range: cannot paginate 0 txs with offset 0 and limit 100: invalid request: invalid request",
    "details": []
}

I have my own node, but public response is the same: sei-rest.publicnode.com/cosmos/tx/v1beta1/txs/block/202296839.

To Reproduce
Steps to reproduce the behavior:

1. Make GET request on /cosmos/tx/v1beta1/txs/block/202296839 (block with no transactions)
2. See error

Expected behavior
It should response with info about block
