Maximum call stack size exceeded, using version 11.0.0 with Node 14.16.0 and Federation
Hello,

When I ```npm ls graphql-upload```:
```
apollofederation@1.0.0 /home/ian/Sites/project-gnosis/apollofederation
└── graphql-upload@11.0.0 
```
Here is my React Uploader component, I tried to follow the instructions on the README for using a File:
```
const Uploader = () => {
    const uploadMessage = 'Finally, please upload a PDF:';

    function onChange({ target: { validity, files: [file] } }) {
      if (validity.valid) uploadPDF({ variables: { file } });
    }

    return (
      <form encType="multipart/form-data">
        <label htmlFor="uploadButton">{uploadMessage}</label>
        <input
          name="uploadButton"
          type="file"
          accept=".pdf"
          // ref={pdfInput}
          onChange={onChange}
        />
        <button type="submit">upload</button>
      </form>
    );
  };
```

```
