problem with update

[FrancescoIoppolo]

When I try to update the data: Version deletes my entire collection
This is my function:

void setVersion() {

  std::vector<struct fb_esp_firestore_document_write_t> writes;
  struct fb_esp_firestore_document_write_t update_write;
  fb_esp_firestore_document_write_type_update,
  update_write.type = fb_esp_firestore_document_write_type_update;
  FirebaseJson content;
  String documentPath = "device/" + deviceId;
  content.set("fields/version/stringValue/", VERSION);
  update_write.update_document_content = content.raw();
  update_write.update_document_path = documentPath.c_str();
  writes.push_back(update_write);

  if (Firebase.Firestore.commitDocument(&fbdo, FIREBASE_PROJECT_ID, "" /* databaseId can be (default) or empty */, writes /* dynamic array of fb_esp_firestore_document_write_t */, "" /* transaction */))
    Serial.printf("ok\n%s\n\n", fbdo.payload().c_str());
  else
    Serial.println(fbdo.errorReason());
}

This is my collection:

Wrong repository, you should ask the question here.

You should assign update masks.

Please read this documentation for updateMask.

You should read the Firestore REST API documentation for the related API used in this library.
