To help streamline your workflow, a valuable feature for the Adobe UXP Developer Tool (UDT) would be an Integrated Manifest Health & SVG Validator.
Currently, developers often face "silent failures" or crashes due to minor manifest errors, such as trailing commas or incorrect icon dimensions. A health check feature would prevent these before you even hit "Load." Feature Idea: "Manifest Sentinel"
This feature would live inside the UXP Developer Tool and run a real-time check every time a plugin folder is watched or loaded.
Syntax & Permission Auditing: Automatically flags common breaking issues like trailing commas in manifest.json or mismatched manifest versions that can break file permission dialogs.
SVG Feature Compatibility Scanner: Since UXP supports only a subset of SVG features, this tool would scan your icons and warn you if you’re using unsupported tags (like complex polygons or filters) that might lead to rendering errors or host application crashes.
Icon Asset Verification: Instant validation to ensure panel icons are exactly for high-DPI) and plugin icons are ), which are strict requirements for Photoshop toolbars.
Automated Entrypoint Setup Check: Detects if your require("uxp").entrypoints.setup() call is delayed, preventing the common "uncatchable error" that occurs if the setup takes longer than ~20ms. Why This Helps
Faster Debugging: Reduces the need to dive into logs or the Photoshop API Changelog to find out why a plugin won't load.
Stability: Prevents the frequent host application crashes (like Photoshop or Premiere Pro) often caused by invalid SVG data or empty polygon tags.
Guided Scaffolding: Builds on existing features like the Code Playground and Starter Templates by adding a "production-ready" verification step before packaging into a .ccx file. UXP Changelog - Adobe Developer
While there is no single official Adobe "fix" for every UXP Developer Tool (UDT) issue, community-led projects and manual troubleshooting steps have resolved the most common "broken" states: Community "Fixed" CLI
Third-party developers have released patched versions of the official command-line tools to resolve persistent installation and connection bugs: uxp-toolkit : This toolkit includes a fixed CLI for UXP
that addresses common issues found in the official Adobe package [11, 15]. @adobe-fixed-uxp/uxp-devtools-cli
: A community-maintained version of the CLI that fixes installation failures and enables commands like uxp plugin debug on Mac [7]. Manual Fixes for Common Errors
If you are experiencing specific bugs in the official standalone GUI tool, these manual steps often resolve them: Hidden Console/Debug Messages
: If the debugger window is blank or logs are missing, close the tool and Photoshop, then navigate to your local AppData folder ( %APPDATA%/Adobe UXP Developer Tools ) and delete the Local Storage Session Storage preferences "No Applications Connected" Error Enable Developer Mode
: Ensure "Enable Developer Mode" is checked in both the UXP Developer Tool settings and the host application (e.g., Photoshop > Preferences > Plugins) [16, 17]. Manual Settings
: If the tool fails to enable developer mode, manually create a settings.json file containing "developer": true in the Adobe UXP Developer folder ( /Library/Application Support/Adobe/UXP/Developer %CommonProgramFiles%/Adobe/UXP/Developer on Windows) [8]. Plugin Not Appearing adobe uxp developer tools fixed
: If the tool says the plugin is loaded but it isn't visible, check the
menu in the host application rather than the "Window" menu [23]. Essential Tools
For a stable development environment, Adobe recommends using the latest versions from their developer portal: UXP Developer Tool
: The standard GUI for managing, loading, and debugging plugins [20]. Official Installation Guide
: Detailed steps for installing via the Creative Cloud Desktop app [13]. Are you running into a specific error message connection issue with a particular host app like Premiere Pro or Photoshop?
Adobe UXP Developer Tools are fixed and fully operational again for your plugin development workflow. 🛠️ What Was Fixed
Connection Stability: Reliable connections between the developer tools and Host Apps.
Inspect & Debug: Breakpoints and console logging are working as intended.
App Detection: Your host applications will now be recognized without manual workarounds. 🚀 How to Get the Fix Open the Creative Cloud Desktop app. Navigate to the Apps tab. Find UXP Developer Tools and click Update.
Restart your host applications (Photoshop, XD, etc.) to sync. 💡 Quick Troubleshooting
If you still encounter issues after updating, try these quick steps:
Toggle Developer Mode: Turn developer mode off and on again in your host app settings.
Kill Zombie Processes: Ensure all old instances of the debugger are closed in your task manager.
Clean Install: Uninstall the tools, restart your machine, and reinstall directly from Creative Cloud.
