Trait Error using LSTEventSource

[chaimain]

I am getting the following TraitError while using LSTEventSource to read data from a file.

TraitError                                Traceback (most recent call last)

----> 5         max_events=10
      6     )

    103 
    104         # set up logging

TraitError: Traitlet does not exist: tool

Can someone help me regarding this issue?

This is due to a change in ctapipe.

I will fix this here.
