Error in Kickstart solidity code. "false transaction mined but execution failed" in createRequest().

[Sunny-64]

The error was caused due to the following line of code. I'm using solidity version ^0.8.0 and i was getting that error because requests Array is dynamic and we're trying to access it's index that doesn't even exist.

Request storage r = requests[numRequests++];

fix :

Request storage r = requests.push(); 

Thanks for detailed explanation btw I got stuck for a while finding the correct version of the code.
