Gas Estimation failed: error

Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?

Hi! i have been trying to test the fund function on testnet and have enough eth but still getting this error. can anyone please help me to understand this?

Hi. @Blockchainkid in other to help you solve the issue it requires you attach the code logic of fund() function, the issue primarily in most cases is due to mathematical errors in logis

[Blockchainkid]

function fund() public payable{
            
            
            require (msg.value.getConversionRate() >=MINIMUM_USD , "not enough");
            funders.push(msg.sender);
            addrssToAmount[msg.sender]+= msg.value;     
           
          }

Thanks for the reply ser. could you please check ?

@Blockchainkid

getConversionRate

Where did you get this from? It is not a build in function... (see here: https://docs.soliditylang.org/en/develop/units-and-global-variables.html)

[Prosperity]

if this is all you have

@Blockchainkid

this will not provide any error as you are only pushing into an array

@Blockchainkid

            addrssToAmount[msg.sender]+= msg.value;     

this also will not provide any error if you have msg.value that you are trying to add to the user amount
funders.push(msg.sender);

@Blockchainkid

so if you can, can you provide where the conversion rate is coming from?
and your implementation seems to be wrong too.
require (msg.value.getConversionRate() >=MINIMUM_USD , "not enough");
