JsonException org.openqa.selenium.json.JsonException

The JsonException occured when any action/operation return values are not being able to parse by selenium client.

Example

It is an example code of JsonException which has been thrown by selenium client if the response data is not in Json format.

1private static Object asAtomLocatorParameter(Object object) {
2  if (object instanceof WebElement) {
3    return object;
4  }
5  if (!(object instanceof By)) {
6    throw new IllegalArgumentException("Expected locator to be either an element or a By: " + object);
7  }
8  assertLocatorCanBeSerialized(object);
9  Map < String, Object > raw = JSON.toType(JSON.toJson(object), MAP_TYPE);
10  if (!(raw.get("using") instanceof String)) {
11    throw new JsonException("Expected JSON encoded form of locator to have a 'using' field. " + raw);
12  }
13  if (!raw.containsKey("value")) {
14    throw new JsonException("Expected JSON encoded form of locator to have a 'value' field: " + raw);
15  }
16  return ImmutableMap.of((String) raw.get("using"), raw.get("value"));
17}

Solutions

• Verify requests made by selenium client
• Add try,catch block to handle the error
• Update Selenium version to latest
