i am trying to send a recently in app - captured photo by mail and am encountering the following error:
(for the mailing functionality i am using this module : var Mailer = require('NativeModules').RNMail;
I am trying to send a photo by mail with the help of this module and get the following error:
index.ios.bundle:28842Exception '-[MFMailComposeInternalViewController addAttachmentData:mimeType:fileName:] attachment must not be nil.' was thrown while invoking mail on target RNMail with params ( { attachment = { name = Ladunek; path = "assets-library://asset/asset.JPG?id=3B7DBB2E-1271-4D86-A5F2-A0CEEE7CC4DE&ext=JPG"; type = jpg; }; body = "body"; isHTML = 1; recipients = ( "placeholder@mail.com" ); subject = Ladunek; }, 9 ) This is the invoking code :
.then((data, path) => { console.log(data) console.log(data.path) Mailer.mail({ subject: 'Ladunek', recipients: ['placeholder@mail.com'], body: 'body', isHTML: true, // iOS only, exclude if false attachment: { path: data.path, // The absolute path of the file from which to read data. type: 'jpg', // Mime Type: jpg, png, doc, ppt, html, pdf name: 'Ladunek', // Optional: Custom filename for attachment } }, (error, event) => { if(error) { AlertIOS.alert('Error', 'Could not send mail. Please send a mail to support@example.com'); } }); }) Is the path invalid? Or might it be something else.
EDIT
I am obtaining the file path with this module react-native-camera like so:
Event:
takePicture() { this.camera.capture() .then((data, path) => Element:
<Camera ref={(cam) => { this.camera = cam; }} style={{ flex: 1, justifyContent: 'flex-end', alignItems: 'center', height: 400, width: Dimensions.get('window').width }} aspect={Camera.constants.Aspect.fill}> <Text style={{ flex: 0, backgroundColor: '#fff', borderRadius: 5, color: '#000', padding: 10, margin: 40 }} onPress={this.takePicture.bind(this)}>{cameraIcon}</Text> </Camera> UPDATE2
After including an obj-c file for uri to path transformation I am receiving the following error now:
ExceptionsManager.js:76 JSON value '<null>' of type NSNull cannot be converted to NSString Did I "remove" the wrong lines from the following code? :/
Obj-c File content:
#import "RCTBridgeModule.h" #import <AssetsLibrary/AssetsLibrary.h> #import <UIKit/UIKit.h> @interface ReadImageData : NSObject <RCTBridgeModule> @end @implementation ReadImageData RCT_EXPORT_MODULE(); RCT_EXPORT_METHOD(readImage:(NSString *)input callback:(RCTResponseSenderBlock)callback) { // Create NSURL from uri NSURL *url = [[NSURL alloc] initWithString:input]; // Create an ALAssetsLibrary instance. This provides access to the // videos and photos that are under the control of the Photos application. //ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init]; // Using the ALAssetsLibrary instance and our NSURL object open the image. //[library assetForURL:url resultBlock:^(ALAsset *asset) { // Create an ALAssetRepresentation object using our asset // and turn it into a bitmap using the CGImageRef opaque type. //CGImageRef imageRef = [asset thumbnail]; // Create UIImageJPEGRepresentation from CGImageRef // NSData *imageData = UIImageJPEGRepresentation([UIImage imageWithCGImage:imageRef], 0.1); // Convert to base64 encoded string // NSString *base64Encoded = [imageData base64EncodedStringWithOptions:0]; callback(@[url]); //} failureBlock:^(NSError *error) { //NSLog(@"that didn't work %@", error); //}]; } @end 1 Answers

I never used this module before, but it looks like it expects absolute path of the file, however you are providing a file uri.
How are you obtaining this file uri?
Try using react-native-get-real-path module to see if it helps, you can find it here: react-native-get-real-path
i.e. convert your file uri to obtain real path, and use that as path
