Github rest api post label gives error for array input

We are hosting GitHub enterprise for our development. I am able to access the reset api and create jira, create PR etc.

When I try to add label to my PR, it gives error for array.

curl -X POST -u githuser:gittoken https://api.github.mycompany.com/repos/team/repo/issues/560/labels -H "Content-type: application/json" -k -d '{"labels": ["bug"]}' -H "Accept: application/json"
{
  "message": "Invalid request.\n\nFor 'links/2/schema', {\"labels\"=>[\"bug\"]} is not an array.",
  "documentation_url": "https://developer.github.com/enterprise/2.13/v3/issues/labels/#add-labels-to-an-issue"
}

I check, bug is valid label.

```
curl -u githuser:gittoken -X GET \
https://api.github.mycompany.com/repos/team/repo/labels

From my understanding of the docs, you should directly send an array (which is valid JSON), without wrapping it in an object. That is ["bug"] instead of {"labels": ["bug"]}.

So, the proper request should be:

curl -X POST -u githuser:gittoken \
    https://api.github.mycompany.com/repos/team/repo/issues/560/labels \
    -H "Content-type: application/json" -k \
    -d '["bug"]' \
    -H "Accept: application/json"
