body: <p>While upgrading to React 16.9 i am getting the following error. The problem is that i do not have component named: "t". how can i get the real name of it? I don't have unsafe methods on my code so i assume its related to 3rd party lib.</p>

    <li><p>Rename componentWillReceiveProps to UNSAFE_componentWillReceiveProps to suppress this warning in non-strict mode. In React 17.x, only the
    UNSAFE_ name will work. To rename all deprecated lifecycles to their

    your project source folder.</p></li>
