fetch-blob | A Blob implementation in Node.js | Runtime Evironment library

The reason you are getting DocumentPicker undefined is the react-native-document-picker version 8.0.0 has been updated since version 2.1.0 which code you've posted.

According to the library doc, you have to import the DocumentPicker differently. And the util DocumentPickerUtil is also not available to the updated version. For react-native-document-picker version 8.0.0 you have to import in the following way

import DocumentPicker, { types } from 'react-native-document-picker';

And also DocumentPicker.show method is no longer available you have to use the DocumentPicker.pick method.

iOS

1. Run command react-native unlink rn-fetch-blob
2. Add CFBundleIdentifier in info.plist file

The docs are actually wrong. For everybody having the same problem:

I recently encountered a similar issue with boost after updating react native. After the panic wore off, and some good coffee, I was able to resolve by doing the following:

1. Open the /ios/.xcworkspace file in Xcode.
2. Raise the iOS Deployment Target (in my case I only bumped to 10).
3. Product > Clean Build Folder, then Product > Run.
4. Locate the boost error in the issue navigator and identify which pod the error is listed under (in my case it was RNReanimated).
5. Update the node package related to the pod (in my case, npm update react-native-reanimated
6. Finally, run pod install

After performing those steps, I was able to get my project up and running again.

It is because of target SDK updated to 30, some features (eg: Speech recognition,TTS) works in from android 11 device only after adding following code in our AndroidManifest.xml

The advice the warning message is giving refers to the package.json of your code as opposed to the package.json for the fetch library. If you don't already have a package.json at the root of your project (that is ./package.json instead of ./node_modules/node-fetch/package.json) you will need to create one. If you already have a ./package.json file or once you have created one you just need to add the line:

You need to set the correct Content-Type for each object in S3, for example application/pdf or image/png.

You can do this when uploading the object, or you can use the AWS S3 Console to modify it afterwards. Note that Content-Type is considered metadata.

Setting the correct Content-Type on the object means that when the object is served by S3 or CloudFront, that Content-Type will be conveyed to the client, allowing it to decide to display or download, as appropriate.
