## Example upgrade

Now modify the file `main.py` to receive a body from a `PUT` request.

Declare the body using standard Python types, thanks to Pydantic.

```Python hl_lines="4  9-12  25-27"
from typing import Union

from fastapi import FastAPI
from pydantic import BaseModel

	if err != nil {
		writeErrorResponse(ctx, w, toAPIError(ctx, err), r.URL)
		return
	}

	aclHeader := r.Header.Get(xhttp.AmzACL)
	if aclHeader == "" {
		acl := &accessControlPolicy{}
		if err = xmlDecoder(r.Body, acl, r.ContentLength); err != nil {
			if terr, ok := err.(*xml.SyntaxError); ok && terr.Msg == io.EOF.Error() {
				writeErrorResponse(ctx, w, errorCodes.ToAPIErr(ErrMalformedXML),
					r.URL)
				return
			}

  const resp = await github.rest.issues.create({
    owner,
    repo,
    assignees: assignee_logins,
    title: `Issue created for Rollback of PR #${pr_number}: ${pr_title}`,
    body: `Merged PR #${pr_number} is rolled back in ${rollback_commit}.
    Please follow up with the reviewer and close this issue once its resolved.`
  });
  return `Issue created: ${resp.data.number} with Title: ${resp.data.title}`;

		writeErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrAdminConfigTooLarge), r.URL)
		return
	}

	password := cred.SecretKey
	kvBytes, err := madmin.DecryptData(password, io.LimitReader(r.Body, r.ContentLength))
	if err != nil {
		adminLogIf(ctx, err)
		writeErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrAdminConfigBadJSON), r.URL)
		return
	}

	subSys, _, _, err := config.GetSubSys(string(kvBytes))

  }
