Ingest error breaks build

[caufieldjh]

Describe the bug

An error occurs during the transform phase of the build:

13:32:36  + python3.8 run.py transform
13:36:57  WARNING:koza.model.config.source_config:Could not load dataset description from metadata file

13:37:05  koza_app: <koza.app.KozaApp object at 0x7f5d91d55a90>

This seems to be an error in transforming the drugcentral-dti. Not certain why it's happening now but it may be KGX related, as the most recent change unpinned KGX version.

To Reproduce

See Jenkins build 66. Happened in build 65 too.

Confirmed that this ingest is problematic:

I think some of the values for ACT_VALUE are just empty, maybe even if there's a value for ACT_TYPE. Try a try.
