Error updating extension in Adobe Exchange
Hi! I have an extension for Adobe Illustrator published in Adobe Exchange but when I want to publish a new version from https://partners.adobe.com/exchangeprogram/creativecloud (Dashboard > "ExtensionName" > Create New Patch) I get the following error, of which I have not been able to find more information anywhere:

The extension is built following this structure:
https://github.com/Adobe-CEP/Getting-Started-guides
And then I generate the .ZXP using ZXPSignCMD v4.1.103-win64
I would appreciate any help
