@AwaisTahseencode make the minAmount public so that other functions can use it and you have to multiply the 1e18 part with 50. When returning price multiply it with 1e10 as 8 decimals are already there (making it a total of 18 decimals)

uint256 public minAmount=50 * 1e18;
// rest of the code

return uint256(price * 1e10);

Also, you may/should refer this

@AwaisTahseencode also make sure you are sending enough wei in your FundMe, as of now the price of 1 ETH is $1,122.44, so 50/1,122 is 0.044, converting this to wei it comes out to be 44000000000000000, rounding off it to 46000000000000000 for safe measure. So now if you send 46000000000000000, it should run without any issue, do check you have enough credit in your metamask too :)

Thank You so much !!!!!

@AwaisTahseencode if that resolved your query, do mark this as answered so that other people could easily skim through the unanswered questions to answer to :)

This is a generic error for not meeting a require/if statement.

Some times its thrown if the your trying to call a function that will fail due to not having ETH.
