Error on set with array of strings

Current behavior

“com.facebook.react.bridge.ReadableNativeArray cannot be cast to java.lang.String”

When passing an array of string to set [“90:FD:9F:73:11:48”]

If I stringify / parse, like in the legacy, it’s OKAY

Expected behavior

Should work

Repro steps

import AsyncStorageFactory from "@react-native-community/async-storage";
import LegacyStorage from "@react-native-community/async-storage-backend-legacy";

const legacyStorage = new LegacyStorage();

export type StorageModel = {
  bluetoothDevices: string[];
};

const storage = AsyncStorageFactory.create<StorageModel>(legacyStorage, { errorHandler: console.log, logger: console.log() });

export default storage;

Environment

• Async Storage version: ^2.0.0-rc.1
• React-Native version: 0.61.5
• Platform tested: Only tested on android
• Logs/Error that are relevant:

“com.facebook.react.bridge.ReadableNativeArray cannot be cast to java.lang.String”

In relation to this, I have found a problem that does not catch when writing fails.

    storage
      .set("test", ["a", "b", "c"])
      .then(async () => {
        // Processing to be called when writing is successful.
        const array = await storage.get("test");
        console.log("set success");
        console.log(array);
      })
      .catch(() => {
        // Processing to be called when writing fails.
        console.log("set error");
      });

Execution result

# set success
# null

My environment is the same as the topic contributor.

“Legacy Storage” is actually using current version of AsyncStorage (v1). So every value has to be stringified before saving and parsed before reading.
