title: Request failed with status code 423 - React Project
body: <p>I am trying to run an old react app, it compiles successfully on Terminal but on the browser it does not run and gives me this message &quot;Request failed with status code 423&quot;</p>
  <p>I am a beginner, I have searched and found this:
  The 423 Locked status code means the source or destination resource of a method is locked. This response SHOULD contain an appropriate precondition or postcondition code, such as ‘lock-token-submitted’ or ‘no-conflicting-lock’.</p>
  <p>But I don't know what should I do. Any idea or solution?</p>
