Reconnect SharePoint data sources after import

Fix SharePoint connection prompts and confirm the app points at the destination site, list, libraries, and supporting lookup lists.

Quick answer

In short

Power Apps may ask you to reconnect SharePoint data sources after import. Reconnect every primary and supporting list to the destination site before testing the app.

Most likely cause

Power Apps stores data source references differently than Form Migrator’s setup screen, so the maker may need to reauthorize or select the list again in Studio.

What to do next

Open Data in Power Apps Studio, repair each SharePoint source, and confirm dropdown lists return rows.

What to reconnect

  • Primary SharePoint list or library.
  • Supporting lookup lists used by dropdowns.
  • Role/user lists used by person selector patterns.
  • Any library or list referenced by buttons or formulas.

How to verify

  1. Open the Data panel.
  2. Look for warning icons on SharePoint data sources.
  3. Reconnect or remove/re-add the affected data source.
  4. Preview a screen that uses the source.
  5. Open dropdowns and submit a test item.

Permissions matter

The maker importing the app needs enough access to create or repair the connections. End users also need read/write access to the SharePoint lists and libraries that the app uses.
