Getting error: execution reverted ass gas estimation failed

[Tarang-16]

This is my code. It is getting deployed but when I click on fund by entering 0.05 eth in wei, it doesn't run. please help!

// get funds from users
// withdraw funds
// set a minimum funding value in USD.

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

@Tarang-16 Also add your price converter file code above.

@Tarang-16 You are using ETH/USD mainnet price feed address, you should use this one 0xD4a33860578De61DBAbDc8BFdb98FD742fA7028e ETH/USD Goerli address
