> From:

> 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:
> [ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.4.0:java
> (default-cli) on project pubsub-bigquery: An exception occured while
> executing the Java class. null: InvocationTargetException: projectId -> [Help
