Upload - uid is set even if provided - issue when fileList is immutable from ReduxToolkit selector | Cannot assign to read only property 'uid' of object '#<Object>'

• I have searched the issues of this repository and believe that this is not a duplicate.

Reproduction link

Steps to reproduce

Check reproduction link - there is my explanation of the problem.
The problem exists because I am using ReduxToolkit and getting attachements from the store (I am setting uid property) but this object is frozen (I want only show attached attachements (read-only))

What is expected?

There is react effect to set uid on each file if not provided

file.uid = (_a = file.uid) !== null && _a !== void 0 ? _a : "__AUTO__".concat(timestamp, "_").concat(index, "__");

should be sth like this

if (!file.uid)
   file.uid = "__AUTO__".concat(timestamp, "_").concat(index, "__");

What is actually happening?

Cannot assign to read only property 'uid' of object '#'

^bumping...

Hi Ant team, this is a blocking issue for my application. Please fix.

I'm having the same problem, but downscaling to version 4.7.0 can fix it

我的fileList是从父组件传递过来的，如果直接放到upload属性里面会报uid read only,可以从新赋值解决

componentDidMount() {
    if (this.props.fileList) {
      this.setState({
        fileList: this.props.fileList.map((item, index) => {
          return { uid: item.uid, name: item.name, status: item.status, url: item.url };
        }),
      });
    }
  }

I've met the same problem. When upgrading antd to v4.13.1, the problem disappeared. All works fine.

Maybe v4.12 has this problem and v4.13 has already fixed it?

升个级试试。
