I am getting this warning and I don't understand what it means - UserWarning: Task <Task: pack_ds_data> has retry settings but some upstream dependencies do not have result types.

Hi Trevor - this warning is letting you know that an upstream dependency of your

pack_ds_data

task is not configured to persist / checkpoint its output anywhere. This means that if your

pack_ds_data

task needs to retry, and for some reason it ends up retrying in a new process, it will not have access to the inputs that were provided. In practice this is rare, but it could occur (hence the warning)
