injectLogger: %v

Error message

injectLogger: %v

What it means

injectLogger installs the siyuan.logger object into the plugin's goja runtime; this error wraps any panic raised while creating or registering the logger API (rt.NewObject, logger.Set of trace/debug/info/... wrappers). Like injectEvent, it indicates an internal fault during plugin runtime bootstrap rather than a plugin-code mistake, and typically aborts plugin initialization.

Solutions

1. Restart the kernel so the plugin runtime is rebuilt cleanly
2. Update kernel and plugins to compatible versions
3. Inspect kernel logs for the wrapped panic detail (%v) to find the failing logger registration
4. Isolate by disabling plugins one by one to find one corrupting the worker

try { startPluginRuntime(); } catch (e) { if (String(e).startsWith("injectLogger:")) { restartKernelPluginHost(); } else { throw e; } }

When it happens

Trigger: Panic inside the logger object construction or wrapper registration during plugin injection — e.g. a broken goja runtime, concurrent runtime teardown, or a kernel-side regression in the logger setup path.

Common situations: Plugin worker shutting down while injection is in progress; kernel/plugin version mismatch introducing setup incompatibility; corrupted plugin load sequence after a prior injection failure.
