Uncaught (in promise) ReferenceError: <function> is not definedHowever I am stuck trying to call my function from the onClick event with the following error: Uncaught (in promise) ReferenceError: action is not defined. getInitialState: function() {. return {. teams: [] }, componentDidMount: function() {.
I'm using es6 promises, and I have multiple layers. On runtime, when I don't catch a promise, I have Uncaught (in promise) in my console. But the fact is that I do catch it lower in my code. Fast simplified example : LoginApi.js. var loginDaoCall = loginDao.login(username, password); loginDaoCall. .then(function (res) {.
A promise can be resolve or rejected. If it's if/when it's resolved any then functions will be called. If it's rejected any catch functions will be called. If you don't provide any catch functions then promise might helpfully print that warning.
