Question

Hey all Simple question if I raise an error within a task i e `ValueError` is it possible to recover that traceback error from a state handler Right now I can say this task failed and will be retrying in X minutes but not this task failed for reason Y and will retry in X minutes Or can we pass keyword arguments to a state handler with this signature ``` What I have now def notify on retry task Task old state State new state Retrying gt State Maybe what I want def notify on retry task Task old state State new state Retrying message str gt State Alternative def notify on retry task Task old state State new state Retrying kwargs gt State ```

Try retrieving it with `new state result`

Ohhhhhh okay I can test it out real quick but do you know if `new state result` would be the `ValueError` itself

You can try logging `type new state result ` also and you can pull the exception message with `new state result message` I think
