Is this a new bug in dbt-core?
Current Behavior
If we have a snapshot declared in the fancy new yaml way that is snapping a source - then partial parsing will error when the source is modified.
Expected Behavior
No error.
Steps To Reproduce
Project setup.
Do an initial parse:

--no-partial-parseflag. This is kinda cumbersome in the dbt Cloud IDE though - each save of a file will do a partial parse behind the scenes.Relevant log output

Environment
Which database adapter are you using with dbt?
postgres

This isn't an issue if we stuck to our good old sql file way of declaring snapshots:
