Unable to instantiate from a template using docker image with cookiecutter

Trying to instantiate a service from a component template using an image with cookiecutter I’m facing the same error reported in #5488.

Expected Behavior

I should continue to be able to create the service starting from a component template.

Current Behavior

Im getting the following error in the Publish phase:

The visibility parameter is valid only when the nebula-preview header is provided.

Possible Solution

Steps to Reproduce

1. Clone backstage from main branch
2. Create new application (same behaviour using the original root repo path)
3. Build docker image for the backend using the Dockerfile provided in contrib folder, adding the installation of cookiecutter:

FROM node:14-buster

WORKDIR /app

RUN cd /tmp && curl -O https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tar.xz && \
    tar -xvf Python-3.8.2.tar.xz && \
    cd Python-3.8.2 && \
    ./configure --enable-optimizations && \
    make -j 4 && \
    make altinstall

RUN apt update
RUN apt install -y mkdocs

RUN pip3.8 install mkdocs-techdocs-core

RUN pip3.8 install cookiecutter && \
    apt remove -y build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libsqlite3-dev libreadline-dev libffi-dev libbz2-dev g++ python-pip python-dev && \
    rm -rf /var/cache/apt/* /tmp/Python-3.8.2

COPY yarn.lock package.json packages/backend/dist/skeleton.tar.gz ./
RUN tar xzf skeleton.tar.gz && rm skeleton.tar.gz

RUN yarn install --frozen-lockfile --production --network-timeout 300000 && rm -rf "$(yarn cache dir)"

# Then copy the rest of the backend bundle, along with any other files we might want.
COPY packages/backend/dist/bundle.tar.gz app-config.yaml ./
RUN tar xzf bundle.tar.gz && rm bundle.tar.gz

CMD ["node", "packages/backend", "--config", "app-config.yaml"]

1. Build docker image for the frontend:

FROM nginx:mainline

RUN apt-get update && apt-get -y install jq && rm -rf /var/lib/apt/lists/*

COPY packages/app/dist /usr/share/nginx/html
COPY docker/default.conf.template /etc/nginx/templates/default.conf.template

COPY docker/inject-config.sh /docker-entrypoint.d/40-inject-config.sh

ENV PORT 80

1. Register the component template from https://github.com/projectkerberus/gcp-stack-template
2. Create service from the imported component template, facing the error:

I don’t think so because I try to start from scratch cloning the master branch today. The fix #5488 has been merged 8 days ago.

Thanks @timbonicus, starting from a newer version of backstage it’s working.
