Setting id to task using Google Task API returns 4

Question

I am using Google's Java API for an project.

Strangely, inserting a task without setting an id works fine. However, inserting a task with a id returns a 400 invalid value error. The id is to be used for syncing local data with Google Tasks

I'm pretty sure there's nothing wrong with the algorithm that generates the ids for the task. The same algorithm works perfectly for Google Calendar API.

Am I missing something here?

You may refer with this SO answer. It suggested to pass the id key/value pair together with the title information you are already sending. There's no documentation to indicate this is a required parameter, especially since it is included in the URL. Google requires the id of the task to be passed as a part of url, parameters and body.
