injectServer: %v

Error message

injectServer: %v

What it means

injectServer installs the siyuan.server object (http/ws/es handler slots) into a kernel plugin's goja runtime. A panic inside the injection (e.g. lo.Must0 failing because a property could not be set on a sealed object, or goja runtime misuse) is recovered and wrapped as "injectServer: %v". The plugin load then fails with this error. It indicates a kernel-side injection failure, not a problem in the plugin's JavaScript code.

Solutions

1. Check the full log line for the wrapped panic message to identify the actual panic cause
2. Restart SiYuan and re-enable the plugin; corrupted goja runtime state is transient
3. Update SiYuan to the latest version; this is an internal injection path likely fixed upstream
4. If reproducible, disable the offending plugin and file an issue with the stack trace

// Kernel-side Go code loading the plugin
if err := injectServer(p, rt, siyuan); err != nil {
    return fmt.Errorf("plugin %s load failed: %w", p.Name, err)
}

When it happens

Trigger: A panic during injectServer: lo.Must0 sees a non-nil error from Object.Set / ObjectSeal / ObjectFreeze / siyuan.Set (e.g. the target object is already sealed or the runtime is in a broken state), or any unexpected panic inside the function while loading the plugin.

Common situations: Kernel/plugin host bug or a corrupted plugin runtime state during plugin load; typically hit during SiYuan startup or when enabling a kernel plugin after an abnormal shutdown; rarely caused by user configuration.
