[MohistMC 1.20.1] ImageFrame v1.8.2.0 fails to initialize – Unable to find PlatformScheduler implementation

[kitamaruramito]

Server Environment

Server Type: MohistMC (Forge + Bukkit hybrid)

Forge Version: 1.20.1-47.4.0-universal

ImageFrame Version: 1.8.2.0

Minecraft Version: 1.20.1

What Happened
When starting the server with ImageFrame installed, the plugin enters its onEnable() phase but throws an exception and immediately disables itself. As a result, none of the /imageframe commands are available in-game.

Relevant Console Output

[14:24:47] [Server thread/INFO] [com.mohistmc.MohistMC]: Enabling ImageFrame v1.8.2.0
[14:24:48] [Server thread/ERROR] [com.mohistmc.MohistMC]: Error occurred while enabling ImageFrame v1.8.2.0 (Is it up to date?)

[14:24:48] [Server thread/INFO] [com.loohp.imageframe.ImageFrame]: [ImageFrame] Disabling ImageFrame v1.8.2.0
Steps to Reproduce

Download and run Mohist Minecraft server.

Place ImageFrame-1.8.2.0.jar in the plugins/ folder.

Start the server and observe the console logs.

Expected Behavior
ImageFrame should successfully register its scheduler and enable all commands. The console should show something like:

[ImageFrame] Enabling ImageFrame v1.8.2.0
[ImageFrame] ImageFrame has been enabled successfully.
Actual Behavior
Plugin fails to find a PlatformScheduler implementation, throws IllegalArgumentException, and disables itself immediately.

Additional Notes

This issue does not occur on a standard Paper or Spigot 1.20.1 server.

It appears MohistMC’s Bukkit API layer does not include a compatible implementation for the PlatformScheduler used by InteractiveChat/ImageFrame.

Request

Could you advise whether MohistMC compatibility will be officially supported in a future release?

Are there any known workarounds or configuration changes to supply a valid PlatformScheduler under MohistMC?

Can you paste your complete server startup logs for a closer look?

(Just a reminder that hybrid servers are not officially supported)

I am receiving the same issue for 1.8.4.0 on MC 1.21.7
