TransitionGroup Error with React/Gatsby

opened 11:11PM - 10 Jun 19 UTC

### Description Using the current Auth0-js and Auth0-Lock packages, I was recei…ving an error in TransitionGroup.js that's being used from the Auth0-Lock dependency: react-transition-group ("react-transition-group": "^2.2.1"). My app is built in React (16.8.6) with Gatsby (2.3.31). I fixed the issue so I no longer have the exact line of code, but basically "this.state.children" did not exist so TransitionGroup.js would cause an error which prevented the entire page from rendering. ### Environment Please provide the following: * Lock version: 11.16.2 * Browser version: Chrome 74.0.3729.169 * OS: Windows 10 * Additional extensions/libraries that might be affecting your instance: ### Reproduction As this is a project that can't be viewed by the public yet, I can't link to my repo, but I was able to fix the problem by removing the 'react-transition-group' from the Auth0 dependencies. I used the same method for fixing the errors between React versions from the Auth0 dependencies: "resolutions": { "react": "^16.8.6", "react-dom": "^16.8.6", "react-transition-group": "^4.1.1" }
