I locally built 0.8.26 DataHub reported an error in obtaining the ES data source metadata. I reinstalled the ES plug-in, but there was still a problem. I don't know why

are you sure you specified http/https in the source host

I used the same YML file, and when I used the PIP installed DataHub to get the ES metadata it was successful, I guess it was the es plugin mess. I can't handle it right now
