Error When Uploading IPA to TestFlight Using New Target

I recently created a new target in my project for the Lite version of my app. Now when I go to upload the .ipa to TestFlight so I can distribute it to my designer, I'm getting:

Invalid IPA: The keychain-access-group in the embedded.mobileprovision and your binary don't match.

Seems clear to me the reason this is happening is because of the new target. Does anyone know what exactly do I need to change to get this to work?

How do I import an IPA file into TestFlight?

From the Stores home page, select “App Store Connect users”. Click Publish to TestFlight in the upper-right corner. At the first step of the wizard, you must upload you . ipa file.

I had this same problem. It was caused by having the wrong release code signing identity in the target's build settings. You won't need an entitlements file.
