> A Beam user using DatastoreIO.v1() encountered an error because their pipeline didn't specify a Datastore project via DatastoreIO.v1().read().withProject(..). But the error was not very informative. Even when referencing the source code, it is difficult to trace through the code due to use of AutoValue and ValueProvider.
> The error was:
