Yes, 'error' is an instance attribute of the 'QJsonParseError' object in PyQt5. It stores the error code that is generated when parsing a JSON file. Here's an example of how to use it:
```python
from PyQt5.QtCore import QJsonDocument, QJsonParseError
# create a JSON document
json_string = '{"name": "John", "age": 30}'
json_doc = QJsonDocument.fromJson(json_string.encode())
# check for errors
if json_doc.isNull():
error = QJsonParseError()
error = json_doc.parseError()
print("JSON parsing error:", error.errorString())
else:
print("JSON parsing successful!")
```
In this example, if there is an error while parsing the JSON string, the 'error' attribute of the 'QJsonParseError' object will store the error code, which can be accessed using 'error.errorString()'.
