Couldn't find any Elasticsearch data

[pilgrimage80]

I filled project.json and setup.cfg according to the steps in the document to pull Gitlab data, but I get the following error with localhost:5601, what could be the reason?

No default index pattern. You must select or create one to continue.

Couldn't find any Elasticsearch data
You'll need to index some data into Elasticsearch before you can create an index pattern.
