The second argument of the GRAB() function is based on JSONPath.

However, JSONPath is used to extract data from JSON documents, while the GRAB() function extracts data from frames. Under the hood, a frame wraps the whole dataset in brackets [], and that's why you need to use additional operators to extract data, compared to the examples provided in the article on JSONPath.
