Can't add story point and due date to new issue with Jira API

[Roman Kyrychenko]

I created a new project with Jira API.

projectTypeKey: 'software'

projectTemplateKey: 'com.pyxis.greenhopper.jira:gh-simplified-kanban-classic'

When I create a new issue with story point and due date, can't add them.

I've checked `Field Tab` out but can't see story point and due date.
When I added story point and due date in `Field Tab` manually, it works as well.

But these fields aren't in `Field Tab`, I can't add using Jira API.

How to add story point and due date to `Field Tab` using Jira API?

Please help me.
