JIRA.Forms.createCreateIssueForm is not showing combo box for sprint

[Subhajit Bhuiya]

We are using following code to bring Jira's creation dialog. All the fields are working fine except "Sprint " field. It supposed to show a combo to choose but it is not showing anything to choose.

var issueForm = JIRA.Forms.createCreateIssueForm({pid:${projectId}});

var dialog = issueForm.asDialog({windowTitle: 'Create Issue'});

dialog.show();

This is what I got

It is a select field instead of input field and also it is hidden. I have only imported this in my code

$webResourceManager.requireResource("com.atlassian.jira.jira-quick-edit-plugin:quick-form")

Am I missing anything?
