One of the greatest challenges I faced was importing the ethers module into a vanilla js script, I could've solved the issue by simply using react but I wondered why that particular error was occurring, I looked at some docs for the syntax and they all seemed correct but the browser would keep sending me the same error of not being able to define the require statement and the import being outside of the module. Also, another issue was after connecting my meta mask account to the lighthouse login, I wasn't able to upload the png file, I'm still looking into it.
