                      Cloud Function annotateImage() returns 'Unexpected token o in JSON at position 1' to native iOS app

                      Asked 2021-Oct-20 at 15:08

                      I am creating an ImageAnnotator for a native iOS mobile app using Firebase Cloud Functions, following the Firebase documentation for the iOS client and Cloud Function. Yet upon calling 'annotateImage' client-side the error 'Unexpected token o in JSON at position 1' is returned. I am using XCode 13.

                      My client code:

                      import Foundation
                      import Firebase
                      import Resolver
                      
                      class ImageAnnotator: ObservableObject {
                        @LazyInjected var functions: Functions
                        @Published var annotatedText: String?
                        @Published var error: NSError?
                      
                        func annotateImage(imageData: Data) {
                          let base64encodedImage = imageData.base64EncodedString()
                      
                          let requestData = [
                            "image": ["content": base64encodedImage],
                            "features": ["type": "DOCUMENT_TEXT_DETECTION"],
                            "imageContext": ["languageHints": ["en"]]
                          ]
                      
                          functions.httpsCallable("annotateImage").call(requestData) { (result, error) in
                            if let error = error as NSError? {
                              self.error = error
                              return
                            }
                            
                            DispatchQueue.main.async {
                              guard let annotation = (result?.data as? [String: Any])?["fullTextAnnotation"] as? [String: Any]
                              else {
                                return
                              }
                              print("%nComplete annotation:")
                              let text = annotation["text"] as? String ?? ""
                              print("%n\(text)")
                              self.annotatedText = text
                            }
                          }
                        }
                      }
                      

                      My index.js cloud function code:

                      const functions = require('firebase-functions');
                      const vision = require('@google-cloud/vision');
                      const client = new vision.ImageAnnotatorClient();
                      exports.annotateImage = functions.https.onCall(async (data, context) => {
                        if (!context.auth) {
                          throw new functions.https.HttpsError(
                            "unauthenticated",
                            "annotateImage must be called while authenticated."
                          );
                        }
                        try {
                          return await client.annotateImage(JSON.parse(data));
                        } catch (e) {
                          throw new functions.https.HttpsError("internal", e.message, e.details);
                        }
                      });
                      

                      What could be causing this error to return from the annotateImage() call?

                      I was able to resolve the error by using the solution suggested here:

                      1. Change the 'features' dictionary value of requestData to an array.
                      2. Pass requestData as encoded string JSON to annotateImage().

                      But still the line

                      guard let annotation = (result?.data as? [String: Any])?["fullTextAnnotation"] as? [String: Any]
                      

                      was returning nil.

                      The line was not correctly parsing the result object. I solved the nil return by serially downcasting result.data to an NSArray, and then index 0 of the NSArray to an NSDictionary. Then I was able to access the fullAnnotatedText field of the NSDictionary as a [String: Any].

                        func annotateImage(imageData: Data) {
                      
                          struct requestData: Encodable {
