I got this error.
after searching. your code does not support almost default network contracts. please tell me am I right?

Error: Network - 97 doesn't have a multicall contract address defined. Please check your network or deploy your own contract on it.

Same here for another network.
I think the problem is that new Ethers uses a BigInt as network ID, and this library uses a switch with numbers to find a match with the enum.
Since switch uses a STRICT equality (=== operator) it doesn't match a number with BigInt.
