From the backend of the service (Back4App) I was able to export all my data for each class/table as json. I then used Studio 3T export wizard to connect to database instance of the Bitnami Parse Server and then imported all the data json files. After the export, I was able to see the data in the data browser on the dashboard and from there all pointer columns seemed okay but whenever I click on such columns, it just open the blank screen of the pointed class as if the row for that pointer doesn't exist. Using the objectId/value of the pointer column, am able to filter the class to get the row. Also another thing I realised was that I am not able to edit any of such imported data but any data I add manually can be edited. I am not sure if these two issues are related.
