I'm trying to send my fitness info from my app to strava via a gpx file created in app (the file get created and populated without any problem). I've done some research but can't seem to find the right answer, everything I found is about Email, message or even airdrop. When I run my code it return me with the file but nothing about uploading the file to strava. The console return me this error as well:

(String) = "The file “” doesn't exist." swift

Here's what I've done so far:

func saveWorkout(_ workout: FirebaseWorkout, completion: @escaping (_ success: Bool, _ error: Error?) -> Void) 
 let gpxString = workout.getGpx()

 do 
 let documentsDir = try FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
 let fileURL = documentsDir.appendingPathComponent("workoutData").appendingPathExtension("gpx")

 print("File Path: (fileURL.path)")

 try gpxString.write(to: fileURL, atomically: true, encoding: String.Encoding.utf8)
 guard let fileData = try? Data(contentsOf: fileURL) else 
 workoutTT().analytics("EXPORT_GPX_ERROR")
 completion(false, nil)
 return
 

 let opts: [String: Any?] = [
 "file": fileData,
 "data_type": "gpx",
 "name": workout.name,
 "description": workout.notes
 ]

 if self.isAuthorized && userSettings.membership.hasFullAccess 
 workoutTT().analyticsEvent(kEventCategoryThirdParty, eventAction: "SAVE_WORKOUT", eventLabel: ThirdPartyApplication.strava.rawValue, eventValue: 1)
 workoutTT().debugLog("Strava: Save Workout")
 self.refreshTokenIfNeeded 
 _ = self.oauthswift.client.post("https://www.strava.com/api/v3/uploads", parameters: opts as OAuthSwift.Parameters, success: (_) in
 workoutTT().debugLog("Strava: Save Workout Success")
 completion(true, nil)
 ) (error) in
 workoutTT().debugLog("Strava: Save Workout (error.localizedDescription)")
 completion(false, error)
 
 
 else 
 completion(false, nil)
 

 catch 
 workoutTT().analytics("GPX_CONVERT_CATCH_ERROR", debug: true, timestamp: true, doPrint: true)
 // failed to write file – bad permissions, bad filename, missing permissions, or more likely it can't be converted to the encoding
 completion(false, nil)
