(node:6223) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)

I experienced this error with v1.1.0. Upon further observation, this is due to @actions/core version 1.2.3 not supporting non-string inputs for errors.

This can fixed by updating @actions/core ^1.2.3 dependency to @actions/core ^1.2.4
