.IPA General 1019 Error when Uploading

** I recently completed my app and tried uploading the IPA to the Apple App Store first using the Expo command line tools, then using the Transporter app. Both ways I got the following error: **

"Unable to process validateMetadata request at this time due to a general error (1019)"

I’m going to paste the error log below. I have no idea where to even start with diagnosing the problem. I called Apple support and they told me I have a problem with my binary, but that wasn’t very helpful to me. If anyone has any ideas they would be greatly appreciated!
