Failing to put release - concourse

Question

I'm getting the following error when trying to put a release in a private repo.
creating release ReleaseName error running command: POST https://api.github.com/repos/my-org/my-repo/releases: 404 Not Found []
prior to getting this error, I was getting:
error running command: GET https://api.github.com/repos/my-org/my-repo.git/releases: 404 Not Found []
so I know the get is now working, and it's something specific to the POST.
My resource config is as follows (admittedly doctored to protect the innocent)
- name: gh-release
type: github-release
source:
owner: my-org
repository: my-repo
access_token: {{access-token}}
and the put looks like this (again doctored):
- put: gh-release
params:
name: package/name
tag: version/version
tag_prefix: package/tag-prefix
commitish: package/commitish
globs:
- package/*.tar.gz
I know the access token works for the GET, and I've used it with curl successfully.
Any ideas what I might be doing wrong?
UPDATE: fixed indentation.

Answer 1

Turns out that it was a permissions problem. The user that the token was for only had read access to the repository. Using a different user token, or updating the repo access to write fixed the issue.
