I created the pipeline in Blue Ocean, chose to connect to the Git warehouse, after connecting, I added a node arbitrarily, then saved it to the main branch, and then prompted "Error Indexing failed",however, the Jenkinsfile file has been received in the Gitlab warehouse, but after I clicked <Cancel>, I reopened the pipeline and found that the steps I did before were not saved.

I configured the Git credentials for the branch source in the configuration of this project, and then returned to Blue Ocean to save it normally, but this configuration idea seems a bit strange
