Hey,I'm having trouble with remix and an error,can someon help me?

Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
Returned error: {"jsonrpc":"2.0","error":"execution reverted","id":2808947084980558}

 uint256 public constant MINIMUM_USD = 50 * 1e18;
 function fund() public payable {
        require(msg.value.getConversionRate() >= MINIMUM_USD, "Didn't send enough");//1e18 = 1 *10 **18
        funders.push(msg.sender);
        addressToAmountFunded[msg.sender] += msg.value;
        funders.push(msg.sender);
    }

The value I send is 20000000Gwei

while deploying the contract do not send any value
send the value when only interacting with the contract
