This error doesn't appear and working in version 9.3.6
but when i upgrade current next version to latest, then i got the error.
Is it my coding mistake?
Here is my code

These 2 files basemap.js map.js. BaseMap component is Map component's child

The CodeSandbox link provided is a CRA app and does not reproduce the issue.
