GitLab project resource creation returns 400 suddenly

Hi team, our GitLab infrastructure pipeline started returning 400 error when creating new project since this morning

The error message is

│ Error: POST https://gitlab.com/api/v4/projects: 400 {message: {base: [undefined method `alias=' for nil:NilClass]}}
│ 
│   with module.papercut-docs.gitlab_project.repo,
│   on ../../modules/repos/main.tf line 22, in resource "gitlab_project" "repo":
│   22: resource "gitlab_project" "repo" {

The GitLab TF provider is v18.2.0

I checked our resources, there is no place uses alias= property. Do you know where could go wrong?

Thanks Jing
