React-native-fetch-blob: [iOS] Cannot read property 'DocumentDir' of undefined

[pgonzalez]

Hi!
I have an issue when I tried to integrate this module in my code. This error appears at start launch in the simulator/device.
Do you know what can I do?

[wkh237]

@pgonzalez , did you run rnpm link after npm install --save react-native-fetch-blob ? it looks like native module not linked.

[pgonzalez]

@wkh237 yes, I did and I still have this error

[wkh237]

@pgonzalez , I'm still looking into the problem, I've tried creating a new project and install the package, but I could not reproduce the error. If you're developing on IOS, please check the following settings.

Make sure the module is loaded in your .xcodeproj (should be located in ios/APPNAME/APPNAME.xcodeproj)

Make sure the module has been linked, check General -> Linked Frameworks and Libraries

Recompile the .xcodeproj

[pgonzalez]

when I add to Linked Frameworks and Libraries, I get
* BUILD FAILED *

The following build commands failed:
CompileC < AppProjectDir >/ios/build/Build/Intermediates/RNFetchBlob.build/Debug-iphonesimulator/RNFetchBlob.build/Objects-normal/x86_64/RNFetchBlobFS.o RNFetchBlobFS.m normal x86_64 objective-c com.apple.compilers.llvm.clang.1_0.compiler

[wkh237]

Okay, looks like something went wrong when linking native modules, it would be nice if you could provide me a more complete build log and RN version of the project, I believe it would be helpful !

[wkh237]

Thanks @pgonzalez , this is helpful ! I'm think I know where the problem is : )

[wkh237]

@pgonzalez , what your the version of your Xcode? It might be a problem with Xcode version, please check #31 .

[wkh237]

I've published a new version v0.5.6 which removed these problematic code, I think it should be able to solve this problem: )

[alvaromb]

I got rid of this error just rebuilding the project.

[DeveloperAlly]

Was there a solution to this?

[adriantombu]

@AlisonWonderlandApps I just got into this error after installing the package and simply refreshing my app on the iOs simulator. Closing everything and running react-native run-ios again solved my problem :)

[martianmartian]

newbies? read this post. https://blog.nativebase.io/adding-third-party-native-modules-using-react-native-cbcb9e3786ba

[Lmzd]

I had the same issue
Didn't work with react-native link but worked withreact-native link react-native-fetch-blob.
clean the xcode project and rebuild with react-native run-ios
hope this will helpful

Hello i have solved this issue---- when you install the react-native-fetch-blob and link with iOS, it only provide limited lib on native side.

you can to open project from iOS in Xcode then remove the library of RNFetchBlob.xcodeproj from library folder and then again add by right click on library folder from node modules-->react-native-fetch-blob--->iOS folder --->add project RNFetchBlob.xcodeproj then all required file will be there and make sure add lib on build phases also libRNFetchBlob.a

it works for me.

Thanks

First I ran the following commands:

• react-native link react-native-fetch-blob
• rnpm link

Even restarting the simulator, the bundler and clearing cache it did not work.

After that, I have opened the project in Xcode and did the following:

Added the rn-fetch-blob .xcodeproj to the Libraries folder

_Alien Catalog is the name of my project_

Add libRNFetchBlob.a to the list under "Link Binary With Libraries"

Click on your project name on the top-left corner in the files sidebar, then under the main panel there will be several tabs, click on "Build Phases", then expand the "Link Binary With Libraries" pane and click the "+" (plus) button:

• A new window will appear with a search field on top, search for "libRNFetchBlob.a", then select it and click "Add".
• Restart simulator and bundle and try again, it should work fine now.

😧😰

As I'm developing an iOS-only app, I only bothered making it work there, so no clue if it works on Android.

Versions:

{
"react-native": "0.56.0",
"rn-fetch-blob": "github:joltup/rn-fetch-blob#master" // @0.10.8
}

I hope this helps someone with the same problem.
And to the maintainers: thanks for the lib, it is great :)

Any pointers on what to do when this error occurrs when running tests?

[indapublic]

@schumannd Same. Did you find solution?

[schumannd]

Nope, I switched to using an older version of the package. I will start another try to update to RN 57 and newest rn-fetch-blob soon

@schumannd

I'm already using rn-fetch-blob and had errors during tests.

Found solution here

Added __mocks__/rn-fetch-blob.js file with

const existsMock = jest.fn();
existsMock.mockReturnValueOnce({ then: jest.fn() });

export default {
  DocumentDir: () => {},
  ImageCache: {
    get: {
      clear: () => {},
    },
  },
  fs: {
    exists: existsMock,
    dirs: {
      MainBundleDir: () => {},
      CacheDir: () => {},
      DocumentDir: () => {},
    },
  },
};

And tests are passed successfully.

"rn-fetch-blob": "^0.10.13"

After having the same issues, I managed to install react-native-fetch-blob and get rid of the Cannot read property 'DocumentDir of undefined' by:

1. Following the installation steps (I used npm to install the module).
2. Linking the package manually

I think the important part that I was missing even previously is to run pod install for iOS.
For Android, the reason it didn't work for me previously might be related to the fact that I'm using react-native-navigation in my project, which means my MainApplication.java is different to the default one (?). This time I just made sure I have the library initialized in getPackages() method and it just worked.

Here's my MainApplication.java for the reference (notice that it extends Navigation Application. It's content is a mixture of the default MainApplication and the one from React Native Navigation installation guide):

public class MainApplication extends NavigationApplication {

  @Override
  protected ReactGateway createReactGateway() {
    ReactNativeHost host = new NavigationReactNativeHost(this, isDebug(), createAdditionalReactPackages()) {
      @Override
      protected String getJSMainModuleName() {
        return "index";
      }
    };
    return new ReactGateway(this, isDebug(), host);
  }

  @Override
  public boolean isDebug() {
    return BuildConfig.DEBUG;
  }

  protected List<ReactPackage> getPackages() {
    // Add additional packages you require here
    // No need to add RnnPackage and MainReactPackage
    return Arrays.<ReactPackage>asList(
      new MapsPackage(),
      new RNFetchBlobPackage() 
    );
  }

  @Override
  public List<ReactPackage> createAdditionalReactPackages() {
    return getPackages();
  }

  @Override
  public void onCreate() {
    super.onCreate();
    Fabric.with(this, new Crashlytics());
    SoLoader.init(this, /* native exopackage */ false);
  }

}

Hope this helps!

fixed by running react-native link and react-native run-ios
