facing the issue even after degrading the ether version to 5.4.0 tried reinstalling but facing this issue code const provider = new ethers.providers.JsonRpcProvider( "HTTP://127.0.0.1:7545" ); Error TypeError: ethers.contractFactory is not a constructor

@venkatmanish for this error TypeError: ethers.contractFactory is not a constructor you need to add new keyword before the ether.ContractFactory and it ContractFactory with capital C.
