backstage: 🐛 Bug Report: backstage error Missing index for techdocs.

📜 Description

I’ve successfully setup techdocs as follows

*Run backstage in docker and use techdocs by local mode by follow the guide or github issue I found -----app-config.yaml----------------------------------- techdocs:   builder: “local”   generator:     runIn: “local”   publisher:     type: “local” -----Dockerfile part of installing mkdocs----------------------------------- RUN set -xe
    && apt-get update -y
    && apt-get install -y python3-pip RUN pip install --upgrade pip && pip install mkdocs-techdocs-core

👍 Expected behavior

There should be no error. Search bar should work. I’m not sure about “index” in the error. Is it search index or index page/index.md which I have as default in example without changing name. The page is also build&rendered already.

*If it’s also possible, I would like to ask how to adjust techdocs style a bit. For example, add cell border. I try to add global css to make vertical line between column. But I cant make it work. Not sure how it should be done in Backstage.

👎 Actual Behavior with Screenshots

Document is finally rendered. But there’s this error comes up every time I view techdocs.

backstage error Missing index for techdocs. This could be because the index hasn't been created yet or there was a problem during index creation. type=errorHandler name=MissingIndexError cause=undefined stack=MissingIndexError: Missing index for techdocs. This could be because the index hasn't been created yet or there was a problem during index creation.

And search bar says “No results found” which I suspect it’s because of this error too. I try to search: Pag or Page and it shows “No results found”

👟 Reproduction steps

1. Setup techdocs follow the guide
2. Create repo structure as default in the guide.
