When selecting a check box from repeating grid it gives me an system error

I have added a checkbox inside a repeating grid and assigned the property called pySelected.

Also I have added a action set to when on click it refreshes the section.

But from the UI when I tried to select check boxes it gives me system administrator error.

Have you tried to trace it ? Did you check logs while clicking the checkbox.

Can you please share these artifacts.

Hi, Thank you for the suggestion. Issue was solved now. The problem was in the data page I have assigned to the repeating grid. Mode of the data page have to be on editable mode but in my case I have set the mode as read-only and that was the issue.
