Error running the minter

[famictech2000]

After running the npm install and then npm start; im getting the following error: Error: Alchemy URL protocol must be one of http, https, ws, or wss. Recieved: undefined

How do I resolve?

Same here (using node v16.13.2 on macos 10.15.7 Catalina)

This is what npm start returns (in the nft-minter folder):

src/Minter.js
  Line 16:13:  Effect callbacks are synchronous to prevent race conditions. Put the async function inside:

useEffect(() => {
  async function fetchData() {
    // You can await here
    const response = await MyAPI.getData(someId);
    // ...
  }
  fetchData();
}, [someId]); // Or [] if effect doesn't need props or state

In the end, I just tried the same thing the day after and it worked all well.

The problem was related to the .env file. I tried to manually insert the Keys (Pinata, Alchemy) directly into the code and it works.
