### Summary
When we setup an integration by webhook on push events or Tag push or whatever and we trigger the webhook no pipeline are created in CI/CD Pipelines.
### Steps to reproduce
I pulled the latest docker gitlab image.
Then run
```shell
docker run --detach \
--hostname gitlab.dev.com \
--publish 443:443 --publish 11080:80 --publish 11022:22 \
--name gitlab \
--volume /srv/gitlab/config:/etc/gitlab \
--volume /srv/gitlab/logs:/var/log/gitlab \
--volume /srv/gitlab/data:/var/opt/gitlab \
gitlab/gitlab-ce:latest
```
Connect to the root account. Create a project with public visibility. In the admin panel enable the Network , Outbound requests
to "Allow requests to the local network from hooks and services". In the project go to setting integration create a webhook integration
with a jenkins project url, a Secret Token and check the push events and tag push events boxes.
> Be sure to disable auto devops for the project
Now that integration is setup go to your project create a readme and push something in it.
The job should be trigger as we have a webhook for me the CI/CD page stay blank.
### Example Project
https://gitlab.com/Shawcs/test
In this integration configuration information for server and token are false but it's not the important part. CI/CD pipelines is
still empty even after my push.
### What is the current *bug* behavior?
No Pipeline information in CI/CD. See screen below.
### What is the expected *correct* behavior?
Pipeline should appear in CI/CD interface. At least in fail status. See screen below.
