This issue does not seem to follow the issue template. Make sure you provide all the required information.

I was also surprised, since the other functions are generic. As a workaround u can type it for now manually:
protected readonly resumesCollection = collection( this.firestore, 'resumes' ) as CollectionReference<Resume>;and then those calls will infer the type
getDocs(query(this.resumesCollection, where('user', '==', user?.uid)))armando-navarro commentedon Nov 5, 2026
Thanks for filing this. Sorry this sat for years. It is the same question as #3081, so I am answering in one place: the
collection()signature is the Firebase SDK's own, the typed path iswithConverter(), and #3838 updates the README and quickstart, which were showing the call that fails.The full explanation is on #3081. If that does not work for your use case, let me know and I will follow up.
