Issues with Monkey C Language Server in Visual Studio Code for Garmin Development

I am encountering persistent issues while trying to develop with Monkey C in Visual Studio Code for Garmin Connect IQ. Below are the details of the errors and the steps I have taken so far:

  1. Error Messages:

    • "Failed to load SDK supplementary files: null."
    • "Server initialization failed. Message: Pending response rejected since connection got disposed. Code: -32097."
    • "Connection to server got closed. Server will restart."
    • "Monkey C Language Server client: couldn't create connection to server."
    • "Server process exited with code 0."
    • "The Monkey C Language Server crashed 5 times in the last 3 minutes. The server will not be restarted."

  2. Build Error:
    When attempting to build for a device, I receive the following error:

    ERROR: Unable to load devices: null

    The command being executed is:

    C:\Program Files\Java\jre1.8.0_461\bin\java.exe -Dfile.encoding=UTF-8 -Dapple.awt.UIElement=true -jar ...

  3. Environment Details:

    • Visual Studio Code with the Monkey C extension installed (version 1.1.2).
    • Garmin Connect IQ SDK Manager is installed and configured.
    • Java JRE 1.8 is installed and added to the system PATH.

  4. Steps Taken:

    • Reinstalled the Monkey C extension.
    • Verified the SDK path in the Connect IQ SDK Manager.
    • Checked the Java installation and ensured it is accessible.
    • Restarted Visual Studio Code multiple times.

Despite these efforts, the errors persist, and I am unable to proceed with development.

Request for Help:
Has anyone encountered similar issues? If so, how did you resolve them? Any guidance or troubleshooting steps would be greatly appreciated.

    Interesting, it does sound like a bug - maybe your circumstances are different somehow, as the SDK manager does re-download devices for me if I move away the devices folder (%appdata%\garmin\connectiq\devices)

    But then again, even if I do move away the devices folder, I don't get the exact same error message as you (I get a more user-friendly error message, which asks me to redownload devices using the SDK manager)

    Here's something you could try:

    - Exit VS Code completely. Rename %appdata%\garmin\connectiq so that the basically has to redownload *everything* from scratch

    - if your user profile name contains spaces or non-ascii characters, try using a user profile that doesn't have spaces or non-ascii chars

    Here's my %appdata%\garmin\connectiq\devices\:

    (after deleting the devices\ folder and letting the SDK manager redownload it)

    For me, %appdata%\garmin\connectiq has the following structure:

    devices\
    sdks\
    fonts\
    current-sdk.cfg (if you didn't have this file, you'd get an error about being unable to determine the current SDK)
    sdkmanager-* (a bunch of files that the sdk manager uses, but don't affect the build)
    simulator.ini (not needed for the build, should be auto-genned by the simulator once you are actually able to build an app and launch the sim)

    I've downloaded and reinstalled multiple times. When I run the new project command in VSCode, the devices appear and in the SDK manager, the devices appear to be installed. Could you please send me your SDK files as a rar file or a screenshot of our file directory so I can identify the missing files?

    ERROR: Unable to load devices: null

    This indicates that the SDK manager might not have installed the "devices" (device config files). Could you try opening the SDK Manager and seeing if it has any devices installed? There is a setting which will have the SDK Manager update them automatically.

    "Failed to load SDK supplementary files: null."

    I'm guessing this is another symptom of not having devices.
