Hi I think I am hitting a bug, and I am unclear why it’s popping up.

It looks like when I have only 1 shot and that shot is missing a task template this triggers maybe?  
I’m not 100% sure on the cause, hopefully someone here can give me a hand if it’s obvious on your side.

Basically the `shotgun_model` that is returning data for the File Open form is hitting a KeyError and crashing nuke.

The location of the KeyError is here: [tk-framework-shotgunutils/master/python/shotgun\_model/shotgun\_model.py](https://github.com/shotgunsoftware/tk-framework-shotgunutils/blob/91f98f69c728ef024fab0a046ce557c182c521dd/python/shotgun_model/shotgun_model.py#L660)

Here is the traceback:

The `entity.Shot.sg_sequence.Sequence.episode` field was not present in the data that was queried from Shotgun. Most likely the query contains a set list of fields, or ones obtained from the context. Actually you can see [here](https://github.com/shotgunsoftware/tk-multi-workfiles2/blob/f1aabeb5755a063b5b5b62c11fa104fcbacc83ec/python/tk_multi_workfiles/file_form_base.py#L244) how the field list is created. Perhaps there’s more to it than I’m seeing right now.

Can’t remember if two-level-deep references like this work at all.

Hey Mois,

I think I’m daft, I just realized that’s in my workfiles config… and the project I had linked it to didn’t have episodes.

This is 100% my fault 😕

Thanks for your help, it made me run a find on my config which lead me to my own fault 😛
