TypeError: Challenge evaluation failed: can't redefine non-configurable property "document" #309

Hi @codemanki and team,

I am using cloudscraper@4.5.0 and node@10.15.1. Cloudscraper works fine when run in node. Code: 

require('cloudscraper').get('https://sochain.com/api/v2/address/btctest/2N7GbVfHioqGTHEAwftrqSxXf4mk919xySY', (e, _, r) => console.log(r));

Using Webpack, I create one js file (named as index.js) from the cloudcraper module and run it in Firefox 71.0. Code (look here: Tests.zip): 

<!DOCTYPE html>
<html style="height: auto; min-height: 100%;" lang="en-US">
 <head>
  <meta http-equiv="content-type" content="text/html; charset=UTF-8">
  <meta charset="UTF-8">
  <meta content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" name="viewport">
  <title>Tests cloudscraper</title>
  <script src="Tests_files/index.js"></script>
 </head>
 <body>            
   <p><button id="btnCheckMySochain" onclick="checkMySochain()">This will test cloudscraper when clicked.</button></p>      
   <script>
      function checkMySochain() {   
    var cors = 'https://cors-anywhere.herokuapp.com/';
    var options = {
       uri:cors+'https://www.sochain.com/api/v2/address/btctest/2N7GbVfHioqGTHEAwftrqSxXf4mk919xySY',       
       // uri:cors+'https://www.sochain.com/api/v2/address/btctest/tb1qhdx9nylta364u7tkc4qdtyjsekqtw8ml2p29e8',
    };

    mySochain.cloudscraper.debug = true;    

    document.getElementById("btnCheckMySochain").disabled = true;           

    var msg = 'see the results in the web console! (for Firefox: Ctrl+Shift+I)';
    mySochain.cloudscraper.get(options)
       .then(function (htmlString) {
        console.log(JSON.parse(htmlString));
        document.getElementById("btnCheckMySochain").disabled = false;          
        alert('SUCCESS: '+msg);
       })
       .catch(function (err) {
        console.log(err);
        document.getElementById("btnCheckMySochain").disabled = false;          
        alert('ERROR: '+msg);
       });
    }
    </script>
   </body>
</html>

This code works fine for a period of time from approximately 8 GMT+2 to 14 GMT+2. Other times, I get an error:

name: ParserError
message: 
### Cloudflare may have changed their technique, or there may be a bug.
### Bug Reports: https://github.com/codemanki/cloudscraper/issues

errorType: 3

Any help would be greatly appreciated. Thanks in advance. Vasyl

Hi @vvpgrp. Very interesting. Why would it work only in certain periods of time? Most probably this happens because of this code - https://github.com/codemanki/cloudscraper/blob/master/lib/sandbox.js#L18

You could try putting something like:


    const cache = Object.create(null);
    const keys = [];
    const { body, href } = global;

    if(typeof document !== 'undefined') {
        return;
    }

    Object.defineProperties(global, {
      document: {
....

@Codemanki thank you very much for your reply and help! Now cloudscraper is working fine. A little later, when the error reappears, I will try your advice.

codemanki commented 4 years ago

@vvpgrp my pleasure :) Please let me know if that fix helps or not. If it does, I might add it to the source code

Today cloudscraper worked fine at 8 GMT+2, but after 14:36 GMT+2 an error message appeared:

ParserError:
