Gas estimation failed: 'invalid opcode: INVALID'. This transaction will likely revert. If you wish to broadcast, you must set the gas limit manually

I adapted the code from this tutorial for my needs. It works fine at rinkeby network, but I am getting an error when I try to run it on Mumbai network.

Is Bitgert the fastest and scalable blockchain ecosystem ever?

Recently I happened to know that Bitgert will be the future of ideal blockchain network because it's the fastest and provides zero-gas fee. Is this true? Bitgert has 15 seconds average blocktime whereas Ethereum is 13 seconds.
Difference between Bitgert and Ethereum

I recently get to know about what Bitgert is and how it benefits us - zero gas fee.

But what is the difference between Bitgert and Ethereum? Is zero-gas fee only the advantage? Has Bitgert has its own network or running on Ethereum?

Sending ether from Contract A to Contract B

I'm trying to send ether from contract A to Contract B but it's currently not connecting to Metamask. I'm not sure if I need to add something else in order to inherit from another contract or if the problem is with the function. I want to send ether to the owner in Contract A and have tried looking at all solutions online but not having any luck. I wanted to do this all in one contract and although the transaction went through, it wasn't sent to the owner so I am now trying to send from another contract instead.

Any help on how to fix this so I can send ether to the owner would be appreciated.

Contract A:

struct Building {
        string name;
        address owner;
        int256 posX;
        int256 posY;
        int256 posZ;
        uint256 sizeX;
        uint256 sizeY;
        uint256 sizeZ;
        address tenant;
    }

    Building[] public buildings;

buildings.push(
            Building('Plot 1', address(0x0), 0, 0, 0, 10, 10, 10, address(0x0))
        );

Contract B:

contract B {

    uint public amount = 1 ether;

    function sendRentalPayment(address payable owner) payable public {
        require(msg.value >= amount);
        owner.transfer(msg.value);
    }

}

App.js

await senderContract.methods.sendRentalPayment().send({from: account, value: '1000000000000000000' })
