Error on return google recaptcha

Hi,
I have the following code and when I’m sending the fetch it is supposed I have to receive a result similar to the one in the image. Maybe you can guide me on what am I doing wrong? I need the response information.

Backend
import { fetch } from ‘wix-fetch’ ;

export async function getDatos ( ) {
let varURL = `` ;
let varRespuesta ;
let varRespuestaJson ;
let varCaptcha ;

varURL  =  `h t t p s : / / w w w . g o o g l e . c o m / r e c a p t c h a / a p i 2 / r e l o a d ? k = 6 L c 6 r o k U A A A A A J B G 2 M 1 Z M 1 L I g J 8 5 D w b S N N j Y o L D k` ; 
varRespuesta  =  **await**  fetch ( varURL , { 
    method :  'POST' , 
    headers : { 
        'Content-Type' :  'application/json' 
    } 
}) 
. then (( httpResponse ) => { 
    **if**  ( httpResponse . ok ) { 
        **return**  httpResponse . json (); 
    }  **else**  { 
        **return**  Promise . reject ( 'Fetch did not succeed' ); 
    } 
}) 
. then (( json ) => { 
    console . log ( json ); 
} ) 
. **catch** (( err ) => { 
    console . log ( "ERROR" ); 
    //console.log(err); 
}); 

}

Expected result
