unexpected json path cause panic

[LuShan123888]

Hello, Thanks much for the awesome API. It is helping me a lot.

When I call the jsonpath.get function with the following parameters, the program appears panic instead of returning the error through err.

func main() {
	data := make(map[string]any)
	_, err := jsonpath.Get(&data, `[["a","a"],["b","b"],["c","c.c"],["d.d","d.d"]`)
	if err != nil {
		print(err)
	}
}

Result：

panic: runtime error: slice bounds out of range [5:2]
