Code snippet:

const fetchRequest = new FetchRequest('MORALIS_RPC');
const jsonRpcProvider = new ethers.JsonRpcProvider(fetchRequest, this.chainId, { staticNetwork: Network.from(this.chainId) });

const blockNumber = 123456; // replace with some block number
const blockHash = 'abcdef'; // replace with some block hash

// Get block data
const block = await jsonRpcProvider.getBlock(blockNumber, true);

// Get block logs
const filter: FilterByBlockHash = {
        blockHash: blockHash,
        topics: [ethers.id('Transfer(address,address,uint256)')],
      };
const logs = await jsonRpcProvider.getLogs(filter)

I have the same problems.

So the case with get block logs(eth_getLogs) really strange. It was reproduced in ETH mainnet.
