问题 I want to send a JSON of all my docuements in Firestore from my backend created with express The Firestore docs says how to get all documents but the method is with forEach and express can send only once the response.

I'm not using Parceleable so can you confirm that this error is due to the complexity of the object to pass and I must absolutely use the Parcels instead of simple Serializeable?
