<!-- Answer -->
To resolve the 404 error when trying to attach a GitLab connection to a
DevLake project using the API endpoint `POST
/projects/{projectId}/connections/{connectionId}` in DevLake version
v1.0.0-beta10, ensure the following steps are correctly followed:
1. **Create a Project**: Ensure you have created a project in DevLake. You
can do this by visiting the Project page from the side menu and following the
instructions on the user interface.
2. **Add a GitLab Connection**: Make sure you have added a GitLab connection
correctly. This involves:
- Providing a unique connection name.
- Selecting the correct GitLab version (Cloud or Server).
- Entering a valid REST API endpoint URL.
- Using a valid GitLab personal access token with the necessary
permissions (`api` or `read_api`).
3. **Verify Endpoint URL**: Ensure the endpoint URL is correct and ends with
a `/`. For GitLab Cloud, it should be `https://gitlab.com/api/v4/`. For GitLab
Server, it should be in the format `https://gitlab.example.com/api/v4/`.
4. **Check Permissions**: Verify that your GitLab user has the appropriate
permissions and is not a Guest role in the GitLab projects you wish to collect
data from.
5. **Add Data Scopes**: Ensure you have selected the GitLab repositories you
want to collect data from and that they are not excluded due to guest
permissions or being archived.
6. **Test and Save Connection**: After configuring the connection, click
`Test Connection` to ensure it is successful, then click `Save Connection`.
If all the above steps are correctly followed and you still encounter a 404
error, it might be due to an incorrect projectId or connectionId in the API
request. Double-check that the IDs used in the endpoint are correct and exist
in your DevLake setup.
Example API request:
```bash
curl -X POST
http://localhost:4000/api/projects/{projectId}/connections/{connectionId} \
-H "Content-Type: application/json" \
-d '{
"data": {
"projectId": "{projectId}",
"connectionId": "{connectionId}"
}
}'
```
Replace `{projectId}` and `{connectionId}` with the actual IDs from your
DevLake setup.
Additionally, ensure that the connection has been tested successfully using
the `TestConnection` endpoint provided by DevLake. This can help verify that
the connection details are correct and that the necessary permissions are in
place. If the connection test fails, it will provide specific error messages
that can help diagnose the issue
