Postgres: unhandledpromiserejectionwarning _Session

[dplewis]

While running test I saw the following error. Just wanted to make sure there wasn't a bigger issue here.

 it("user sign up class method", (done) => {
    Parse.User.signUp("asdf", "zxcv", null, {
      success: function(user) {
        ok(user.getSessionToken());
        done();
      }
    });
  });

That’s odd maybe because inside TX?

@vitaly-t Is it save to catch the error and ignore it?

[vitaly-t]

Well, if you execute a query without any .then and .catch - that's both unreliable in terms of the data you are getting back, and dangerous, while ignoring any possible errors. Other than that, I don't know any specific of the test, as I've never run those for parse-server.
