Why is the background style substituted with a curved path with a variable in React?

Question

HTML

Hello everyone
Such a problem that I substitute the path in the background and it is some kind of curve substituted

{
                  this.props.messages.map(function(element,i){
                    console.log(element.image) // \images\upload\den\Animals__038809_.jpg
                  return (
                    <li key={i} className="chat-message">
                      <div className="chat-avatar" style={{background: `url(${element.image})`}}> // background: url("imagesuploadÞn\a nimals__038809_.jpg");
                      </div>
                      <div className="chat-message-content">
                        <div className="chat-message-name">
                          {element.name}
                        </div>
                        <div className="chat-message-text">
                          {element.text}
                        </div>
                      </div>
                    </li>
                  )
                })}

That is, in my variable, the path is: \images\upload\den\Animals__038809_.jpg
and as a result, when rendering, it becomes: background: url("imagesuploadÞn\a nimals__038809_.jpg");
With image substitution, there is no such thing in Img
