UPIA Installer Returns "status = -267" When Plugin Name Is Too Short

Hello,

   I wanted to share a small issue I encountered while developing a UXP plugin for Photoshop as my university project. The plugin is a custom 3D panel, and everything worked correctly during development and testing with the UXP Developer Tool.

   The plugin packaged successfully as a .ccx file. However, when installing it through Creative Cloud or the Unified Plugin Installer Agent (UPIA), the installation consistently failed with the following message:

Failed to install, status = -267!

After a lot of trial and error, I discovered that the actual cause was much simpler than I initially expected: the plugin "name" in the manifest contained only two characters.

{
  "name": "3D"
}

Changing the name to any value with at least three characters allowed the plugin to install successfully without any other changes.

   I couldn't find this requirement documented, and the returned error code didn't provide any hint about the actual problem. If this minimum-length requirement is intentional, it might be helpful to document it or return a more descriptive error message instead of the generic status = -267.

   I hope this finding helps improve the developer experience for others who may encounter the same issue. Thank you for taking the time to review this report.

Best regards,
