Hello we are using axios with react native and react-native-signalr lib.
The signalr does something with document due to which axios in isStandardBrowserEnv is not properly determining where its running and tries to read cookies in react native app and fails.
I propose we detect react native from navigator.product as it was introduced in this commit for react native:
[https://github.com/facebook/react-native/commit/3c65e62183ce05893be0822da217cb803b121c61](url)
lib/utils.js
for (var i = 0, l = obj.length; i < l; i++) {
      fn.call(null, obj[i], i, obj);
    }
  } else {
    
    for (var key in obj) {
      if (Object.prototype.hasOwnProperty.call(obj, key)) {
        fn.call(null, obj[key], key, obj);
      }
    }
  }
}
/**
 * Accepts varargs expecting each argument to be an object, then
 * immutably merges the properties of each object and returns result.
 *
 * When multiple objects contain the same key the later object in
 * the arguments list will take precedence.
 *
 * Example:
 *
 * ```js
 * var result = merge({foo: 123}, {foo: 456});
 * console.log(result.foo); // outputs 456
 * ```
 *
 * @param {Object} obj1 Object to merge
 * @returns {Object} Result of all merge properties
