Hi, I’m new to drone and I have a quick question on drone consuming github deployment events.  
I created a simple pipeline to see what I’m working with which just triggers on any event

```auto
kind: pipeline
type: docker
name: testing

steps:
- name: test
  image: busybox
  commands:
  - printenv

```

but then I tried to trigger it via github deployment, and somehow it tried to clone from a tag ref. Is there something I’m doing wrong? or is this a bug?

```bash
curl -X POST \
  https://api.github.com/repos/ ***/*** /deployments \
  -H 'Authorization: Basic *************************************' \
  -H 'Content-Type: application/json' \
  -d '{
  "ref": " ************************************* 695",
  "auto_merge": false
}'

```

```auto
Initialized empty Git repository in /drone/src/.git/
+ git fetch origin +refs/tags/ ************************************* 695:
fatal: Couldn't find remote ref refs/tags/ ************************************* 695

```

Add a filter when the pipeline should trigger.

i.e. for pull\_request at the end of the pipeline:

```auto
trigger:
  event:
    - pull_request

```

or for deployment at the end of the pipeline:

```auto
trigger:
  target:
    - test

```

(this will trigger when deployment towards “test” is triggered).

Note deployment event in github is translated into a “promote” event.

```auto
trigger:
  event:
    - promote

```

Okay… I tried that… The pipeline now looks like this

```auto
kind: pipeline
type: docker
name: testing

steps:
- name: test
  image: busybox
  commands:
  - printenv

trigger:
  event:
  - promote
  target:
  - production

```

Now the drone tries to get from heads ref… which is still wrong

```bash
curl -X POST \
  https://api.github.com/repos/ ***/*** /deployments \
  -H 'Authorization: Basic *************************************' \
  -H 'Content-Type: application/json' \
  -d '{
  "ref": " ************************************* 145",
  "auto_merge": false
}'

```

```auto
Initialized empty Git repository in /drone/src/.git/
+ git fetch origin +refs/heads/ ************************************* 145:
fatal: Couldn't find remote ref refs/heads/ ************************************* 145

```

and when I tried to use a head ref as the target… it just appends a `refs/heads/` as a prefix

```bash
curl -X POST \
  https://api.github.com/repos/ ***/*** /deployments \
  -H 'Authorization: Basic *************************************' \
  -H 'Content-Type: application/json' \
  -d '{
  "ref": "refs/heads/test-triggers",
  "auto_merge": false
}'

```

```auto
Initialized empty Git repository in /drone/src/.git/
+ git fetch origin +refs/heads/refs/heads/test-triggers:
fatal: Couldn't find remote ref refs/heads/refs/heads/test-triggers

```

I’m starting to think that this is an actual bug… and I should put this under the bugs category
