Never get unity logs

The code:
        .withUnityLogger(message => 
          {
            log.debug(`Unity: ${message}`);
            console.log(`Unity: ${message}`);
          })
never gets hit.  When unity does have a problem the error is always: 
{"unityLog":""}

Lately for no apparent reason i'm getting the error that says unity crashed and the log file it says it created is always empty.
