firestore: not returning exact error

[Jason-SP-Chien]

Client

Firestore

Code

In firestore/bulkwriter.go, we saw methods of BulkWriter including Create, Delete, Set, and Update. They do not throw the error returned by newXXXWrites. The error itself is replaced by fmt.Errorf("firestore: cannot XXX doc %v", doc.ID), which cost us time to trace out what really happened inside these operations.

Expected behavior

The error itself should be either wrapped or directly returned.

Actual behavior

It is replaced by an almost useless error message.
