> It's look like load and write json data failed, could you please use gdb
to find which json data indeed cause the load failed. Thank you
Using stream load to put a null list will cause the BE crash.
```java
// set headers
// format = "json"; strip_outer_array = "true" jsonpaths = "XXX" columns
= "XXX"
List<Object> list = new ArrayList<>();
httpPut.setEntity(new StringEntity(list.toString(),
Charset.forName("UTF-8")));
response = httpClient.execute(httpPut);
```
The null list value will cause BE crash.
**Expected behavior**
The BE should return a msg like "json value error" or sth else.
