Incorrect behavior on IOS for call driveApi.files.getBinary(fileId)

[Voznov]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch @robinbobin/react-native-google-drive-api-wrapper@1.2.3 for the project I'm working on.

Problem

It's working awesome for Android. But for IOS there is reader.result which equals data:text/plain;base64,ZmVmMGI3YT... That's why it makes b64 equal to undefined and doesn't call resolve or reject

Solution

Here is the diff that solved my problem:

diff --git a/node_modules/@robinbobin/react-native-google-drive-api-wrapper/api/aux/utils.ts b/node_modules/@robinbobin/react-native-google-drive-api-wrapper/api/aux/utils.ts

       if (typeof reader.result === "string") {
-        const b64 = reader.result.split("data:application/octet-stream;base64,")[1];
+        const b64 = reader.result.split("base64,")[1];
+        if (!b64) {
+          reject({reader})
+        }

         resolve(toByteArray(b64));
