When uploading an iOS application from the browser, the IPA file uploading fails, and the following message is displayed: "Data was not saved due to problems during uploading."
Also, when uploading with the dg command or an API, the following message will be displayed:
“Application create error: invalid XML: PCDATA invalid Char value XX”
There may be an illegal character code included in the Bundle name for some reason (sometimes there are things that can not be visually confirmed such as invisible characters).
Check the value on Xcode and reset it.
