Rename componentWillUpdate to UNSAFE_componentWillUpdate 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.

Issue poping all the time that may need fixing

The original react-lottie library seems to be abandoned and still uses
deprecated React lifecycle methods [1]. These methods will be removed in
React 17.

Hence, migrate to lottie-react instead, which fixes the issue and is
expected to have React 17 support [2].
