Library Name

@google-cloud/firestore 9.0.0

A screenshot that you have tested with "Try this API".

Issue is with the library, not with the API

A step-by-step description of how to reproduce the issue, based on the linked reproduction.

See the linked gist, it is obvious

A clear and concise description of what the bug is, and what you expected to happen.

When validating DocumentReference, the library accesses projectId without triggering lazy initialization which results in exception below. Passing string value works fine. I expect it to work for references as well

A clear and concise description WHY you expect this behavior, i.e., was it a recent change, there is documentation that points to this behavior, etc. **

Documentation does not mention that passing DocumentReference will throw
/**
* Specifies the source as a set of documents.
*
* @PARAM docs The document references.
* @returns A new Pipeline object with the documents as the source.
*/
documents(docs: Array<string | DocumentReference>): Pipeline;
