TypeError: Cannot read property 'unwrapObject' of undefined

It appears with the new version, 30 (I guess starting from 27). It depends on the doc returned, if it contains array of maps or other particular nested structure, it crashes. With a “standard” doc, so without nested object, it works. Works fine until version 26.

Minimal code to reproduce the problem

const firestore = FirestoreApp.getFirestore(email, key, projectId);
firestore.query('carts').orderBy('lastUpdate', 'desc').limit(10000).execute();

Expected Behavior

documents[0].obj; // This returns raw object.

Actual Results

documents[0].obj; 
// TypeError: Cannot read property 'unwrapObject' of undefined
//  at unwrapValue(Document:62:29)
//   at unwrapArray(Document:79:29)
//   at unwrapValue(Document:64:29)
//   at [unknown function](Document:74:31)
//   at unwrapObject(Document:73:49)
//   at get obj(Document:42:25)

Library Version:

30

@marcolong I see the issue. I misunderstood the problem. I got thrown off because you were using the .query functionality. But it was all about unwrapping a nested object. I’ll work on this.

As stated in the Breaking Changes:

Query function names have been capitalized (Select, Where, OrderBy, Limit, Offset, Range).

This change was to avoid conflicts with Firestore Typing documentation.
