Original Apple Developer Forum post.
I'm using Application Loader to upload a hosted IAP (I've done this many times before).
However after the package passes validation I keep getting the error:
ERROR ITMS-3000: "Line 91 column 52: element "in_app_purchase" incomplete; missing required element "product_id""
The IAP target has a IAPProductIdentifier
and it is also set up on iTunes Connect.
Am I missing something or is the upload system down?
