The method get(int) in the type List<Map<String,Object>> is not applicable for the arguments (String)

This error occurs when you try to call the `get` method on a `List<Map<String, Object>>` object with a `String` argument. The `get` method in this context expects an integer argument, representing the index of the element you want to retrieve from the list.

To fix this error, you need to use an integer value instead of a string when calling the `get` method. For example, if you want to retrieve the element at index 0, you would call `get(0)` instead of `get("someKey")`.
