You uploaded the correct Provisioning Profile and Certificate pair, if you check the identity hash it matches with the one you can see in your Keychain, but you still get an error like:

You probably have a configuration in your Xcode project settings which specifies which keychain should be used for the build, your scheme might include something like --keychain /../../xxx.keychain code signing flag and a CODE_SIGN_KEYCHAIN variable set in the .pbxproj.

This might happen if you migrate your Xcode Bot based setup into Bitrise.

To fix the issue you have to remove the keychain selection configurations from your Xcode project settings.
