Cannot read property 'classList' of undefined

When you insert the first record in a grid with pagination or delete the last one, it does not refresh the interface. Attached screen with error "Can not read property 'classList' of undefined" and package.json with components version.

Is it a mistake of the grid?

Thank You

Thanks for contacting Syncfusion support.  
We have checked your packge.json file and found you are using different versions of Syncfusion components which may cause duplicate package in @Syncfusion  folder of node modules. So we suggest you to update the Syncfusion package properly by using the below  steps.  
  1. Please ensure that all Syncfusion components have same version (We can see that you are using ej2-angular-grids and ej2-ng-dropdowns)
  2. Please ensure whether the “node_modules/@syncfusion” folder has no any duplicate packages (ex: “node_modules/@syncfusion/ej2-navigations/node_modules/@syncfusion/ej2-base”).
  3. If yes, please remove the “@syncfusion” folder and package.lock.json files and reinstall the package again.
  4. If you are still facing the issue please share the stack trace of the script error.
  5. Please share the Grid code example
These information will be helpful for us to provide a better solution as early as possible.
