Problem uploading react native app to apple store with transporter

We have recently had a problem uploading an react native update of an app to the apple store with transporter.

To upload we:

1. Run expo build:ios in the project directory to get an IPA file
2. We then upload this file to transporter
3. We deliver the app with transporter <-- Here is were we get the error
4. It appears in the activity section of apple connect

The error in transporter:

ERROR ITMS-90085: “No architectures in the binary. Lipo failed to detect any architectures in the bundle executable.”

We have successfully uploaded and updated an react native app before using this method and don't know what we have done wrong this time.
