   > > > @ruanwenjun Can I understand it this way, our previous logs are just 
the output produced by the task execution. But before execution, he may also 
report an error, but the user cannot view it on the front end, and can only 
find this error in the log file afterwards. so we should do this

   > I suggest not just logging error messages, we should log the execution 
flow。eg:(start_process(success)->buildDAG (success)-> put into task queue 
(success)->handleCommon(failed)). this allows users to more clearly understand 
what went wrong in the execution.
   
   The `error message ` will be user friendly.
