IndexError

The only places I deviate in the code is with my `api_key`, `target_file`, and `target_format`. I get the following error.

```
Traceback (most recent call last):
  File "app.py", line 50, in <module>
    target_id=check(data['id'],api_key)
  File "app.py", line 23, in check
    return value_list[0]['id']
IndexError: list index out of range
```
