修改Ionic Storage中object的部分内容

Question

I'm trying to modify a part of object in Ionic storage. I've got this in Storage:

key : object 
value : {a: "1", b: "2", c: "3"}

I tried to modify a value to 10 with this function:

modifyObject() {
    this.storage.get('object').then(valueStr => {
      let value = JSON.parse(valueStr);

      // Modify just that property
      value.a = '10';

      // Save the entire data again
      this.storage.set('object', JSON.stringify(value));
    });
  }

I've got this error when I try to execute mu function

ERROR Error: Uncaught (in promise): SyntaxError: Unexpected token o in JSON at position 1
SyntaxError: Unexpected token o in JSON at position 1

Your JSON in your value is malformed.

It must be something like this.

key : object 
value : {"a": "1", "b": "2", "c": "3"}
