Worker: maybe waiting forever for null dataclips?

[josephjclark]

I need to investigate this.

Runs might be getting lost because the worker is asking lightning for a null dataclip, and getting an error or crickets back, and maybe generally waiting forever.

TODO:

• check the timeout on load dataclip
• check the error handling on load dataclip
• ensure we don't try to fetch falsy values

[josephjclark]

Two quick learnings:

• the worker only asks for dataclips if initialState is a string. I suppose '' could be a value
• There is no error handling on the getDataClip (and getCredential) channel, so we do need to beef that up
