Lesson 9 -- Error HH110: Invalid JSON-RPC response received: project id required in the url.

[lqpchen]

Hey guys, I basically get the same error as this link here (unsolved): https://stackoverflow.com/questions/74083852/web3-development-patrick-c-error-hh110-invalid-json-rpc-response-received-p

I was deploying the same code as in the github hardhat-smartcontract-lottery-fcc to the Goerli test net (GOERLI_RPC_URL=https://goerli.infura.io/v3 in my .env file) but get the error message: Error HH110: Invalid JSON-RPC response received: project id required in the url.

When I change to GOERLI_RPC_URL=https://eth-goerli.g.alchemy.com/v2/xxxxxxxxxxxxxx, it solves the issue.

My question is: what can I append to GOERLI_RPC_URL=https://goerli.infura.io/v3/ to solve the same issue without relying on alchemy? Thanks!

I ran into the same problem. I had ot use alchemy. It provides you with a node service on the block chain. If you want to access goerli without alchemy you will need to run a node of goerli on your own machine. Or if you want to use infura you will need to get a infura API key
