I have created a 2GP-managed package that includes an Apex class with SOQL queries. But from one SOQL query, which is on a custom object, I am unable to get the data for custom fields from that custom object. I am able to get standard fields from that same custom object. I am just getting blank fields in the Lightning data table.

    - You may have not granted the appropriate field-level security for your custom fields in your package. You need to ensure that the profile or permission set that you are using to access the custom object has read access to the custom fields. Oct 30, 2023 at 9:57
  • Thank you for your respone @TusharJadav I have given read and write permissions for all custom fields on that custom object . But still iam facing that isssue.

  • Make sure that you have records on the custom object that you have queried into the apex. Oct 30, 2023 at 11:49

In the Lightning Datatable Columns, you have missed to add your namespace to the API Name of the fields.

For Example, if your namespace is "testingabc". Any custom field added in the package will have api name as testingabc__fieldapiname__c.

Try adding the datatable columns like this:

      label: "Status", 
      fieldName: "namespace__Workbench_Status__c", 
      type: "text", 
      initialWidth: 180 
      label: "In Use", 
      fieldName: "namespace__Used__c", 
      type: "boolean", 
      initialWidth: 70 
  • Thank you So much @S1th Yeshwanth. It got resolved.
