  • Do the following to resolve this issue

    It looks like when you're setting a template for .skedler index, on doing so, a type _doc is mapped to .skedler by default. Usually, we create an index with the type as skedlerdoc in Skedler. Since _doc is mapped already, we cannot create the index. Can you remove the template for .skedler and try again?

    Or you can simply comment on the elasticsearch_url in reporting.yml and use internal DB for storing the metadata. By doing either one of these, you can bypass the issue.
