Answer 1

It looks like there's an error in your secret key. When I try to run this locally, I get:

.../node_modules/@solana/web3.js/lib/index.cjs.js:9870
      throw new Error('bad secret key size');
            ^

Error: bad secret key size
    at Keypair.fromSecretKey (.../node_modules/@solana/web3.js/lib/index.cjs.js:9870:13)
    at .../index.js:4:26
    at ModuleJob.run (node:internal/modules/esm/module_job:194:25)

So be sure that the base58 version of your private key is correct!
