Deprecated react element warning

I’m getting the below error in my Console when I run a Dash app locally. I get a similar warning for componentWillReceiveProps. Is this something with my app/environment specifically, or is it a Dash thing? I upgraded to Dash 2.0.0 to troubleshoot and still get the two warnings.

Warning: componentWillMount has been renamed, and is not recommended for use. See for details.

* Move code with side effects to componentDidMount, and set initial state in the constructor.
* Rename componentWillMount to UNSAFE_componentWillMount 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.
