Move code with side effects to componentDidMount, and set initial state in the constructor.
Rename componentWillMount to UNSAFEcomponentWillMount to suppress this warning in non-strict mode. In React 17.x, only the UNSAFE name will work. To rename all deprecated lifecycles to their new names, you can run npx react-codemod rename-unsafe-lifecycles in your project source folder.
Please update the following components: Uncontrolled(SideNav)`

The end of the message is "Please update the following components: Uncontrolled(SideNav)". This seems to happen any time the SideNav is rendered.
`getLatitude.js:formatted:1 Warning: componentWillMount has been renamed, and is not recommended for use. See https://fb.me/react-unsafe-component-lifecycles for details.
