About calling the send function exception, but the message is still created

[yalbaba]

Hi man, recently I encountered a problem when using this library. When I use the delay queue, if the delay time is negative, I will call it "delay queue" put:bad command Format exception. Although an exception was thrown, the deferred task was created and eventually consumed. However, the consumption of this error message will cause the downstream service exception. I'm glad to ask the author to answer. Thank you very much.
