Param required while performing in-app action

Hi,

In our application, we have the contacts in a list view from which they can be selected in order to perform bulk action. While performing the in-app action we do not receive the ‘selectedIds’ param as indicated by the URL given below when all the contacts are selected at once as depicted by the first screenshot:

We receive the ‘selectedIds’ param when the contact is chosen individually from the list view as depicted by the second screenshot.

Kindly assist us with the issue faced.

Thanks and regards,
Akshaya
