I try to create deployment via platform API based on the documentation here : https://vercel.com/docs/rest-api/endpoints#tag/deployments/create-a-new-deployment
Since I use gitlab as git repository, here is my body request :
await axios .post( `${process.env.VERCEL_API_URL}/v13/deployments`, { name: "Initial deployment", project: vercelProjectId, gitSource: { type: "gitlab", ref: "main", projectId: vercelProjectId, }, }, { headers: { Authorization: `Bearer ${VERCEL_TOKEN}`, "Content-Type": "application/json", }, } ) .catch((err) => { console.error("Error when deploying project", err.response.data); return err; });The response return error 400 with messages :
error: { code: 'incorrect_git_source_info', message: 'The provided GitLab repository does not contain the requested branch or commit reference. Please ensure the repository is not empty.', gitlabError: '{"message":"404 Project Not Found"}' }I've verified the project is successfully created with correct gitlab repo linked on my vercel dashboard. I also verify the projectId is already correct.
The main branch is also correct (I can select it when try to create manual deployment from dashboard).

Additional Info :
- Gitlab repo is private
- I've already have success deployment with the same repo and branch, but by manual deployment from vercel dashboard
- This project is also created from Platform API by following this docs
