The instruction-page uses '2024-01-22' as the value when creating a Movie-entry which results in deprecation warning below.

If you feel comfortable modifying an imported package you can fix the "Deprecation Error" as follows:

  1. Open node_modules\moment\moment.js
  2. Search for function configFromInput(config) declaration (line 3049 as of this note)
  3. Add the following check just before the final "fallback" else {...}:
   // Additional else if: if `config._i==false`, do nothing
   else if (!config._i) { return; }

This fixed the "Deprecation Error" for me, but is likely not the ideal solution.
