GridComponent: Cannot convert undefined or null to object at Function.keys

Hello,

we are using Grid Component in Angular 10 ("@syncfusion/ej2-angular-grids": "^18.4.49") and we are experiencing a very strange problem.
We are receiving tons of errors (the amount of the errors is growing while you stay on the page, sometimes become over than 100) like this one:

Cannot convert undefined or null to object
    at Function.keys (<anonymous>)
    at ComponentBase.push.HJ9Y.ComponentBase.ngAfterContentChecked (component-base.js:233)
    at GridComponent.ngAfterContentChecked (ej2-angular-grids.js:535)



This is the grid that we are showing:



In attachment you can find the component source code.

Thanks!

Pierpaolo Marturano

Hello Jeremy Carter,

could you tell me what exactly was the issue there? I have the `same problem and can't get it resolved.

Thanks!

MH Martin H. May 5, 2021 02:12 PM UTC

Hi,

Jeremy Carter we would be also glad if you will tell us, where exactly was the issue and how did you resolved it. We have the same problem when calling grid.refreshColumns() or even when calling cd.detectChanges before the refreshColumns().

When using ej2-angular-grids: 19.1.55 together with ej2-angular-base: 19.1.54 it is working. When using latest versions, errors are there - so it was introduced in newer minor version without change on our side.

Thanks!

Hi Steve, 

Thanks for the update. 

Query: could you tell me what exactly was the issue there? I have the `same problem and can't get it resolved. 
 
Based on your query we suspect that the reported script error may occurs when the culture/ locale values are not bound properly in the Grid component. So, for your convenience we have attached the documentation to apply the locale properly in the Grid component, please refer them for your reference. 


If you still face the issue then, please share the below details to find the root cause of the issue. 

  1. Share the Complete Grid code example.

  1. If possible, please try to share the issue reproducible sample..

  1. Please share the screenshot or video demonstration of your requirement.
 
  1. Please let us know have your used locale in your Grid application.
 
  1. Please share the Syncfusion package version.
 
Regards, 
Ajith G.
