Unable to execute integration tests

Question

Getting this error when trying to execute GuestBook tutorial project locally. When executed thru GitPod everything works fine, tho.

Rejected promise returned by test. Reason:

  Error (TypedError) {
    context: undefined,
    type: 'RetriesExceeded',
    message: 'Exceeded 10 attempts for http://localhost:8972.',
  }

I tried to debug it. Found out that the test breaks on these lines:

const alice = await root.createSubAccount("alice", {
    initialBalance: NEAR.parse("30 N").toJSON(),
  });
  const contract = await root.createSubAccount("contract", {
    initialBalance: NEAR.parse("30 N").toJSON(),
  });
