setErrorHandler

Sets a global unhandled error handler.

setErrorHandler(f: (err: unknown) => void): void

Notes

• This method replaces the current handler, if any. it’s not cleared by GlobalContext.clear() either; and must not be set in a test context to allow the test runner to catch unhandled errors.
• The default error handler logs all errors using LogWriter.error() (i.e. app.log.error(...)). Consider using a log sink instead of changing this behavior — refer to app.addLogHandler().

Parameters

• f — A handler function, which should accept a single error argument (with unknown type)
