Spinner not working

[mrjack88]

Hi I can not make the spinner to work. I is throwing this error on runtime:

vendor.js?v=sZBD4ty28krojWTr8aPA_g_AGMpt_Nhz9VS_g69om6M:1 Uncaught Error: Minified React error #130; visit http://facebook.github.io/react/docs/error-decoder.html?invariant=130&args[]=undefined&args[]=%20Check%20the%20render%20method%20of%20%60Login%60. for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

I am using it like this:

{
       this.state.isShowingModal &&
       <ModalContainer onClose={this.handleClose}>
         {
           this.state.isShowingModal ?
           <ReactSpinner color="white"/> :
           <ModalDialog onClose={this.handleClose}>
             <h1>Dialog Content</h1>
             <p>More Content. Anything goes here</p>
           </ModalDialog>
         }
       </ModalContainer>
     }
