The Senzing POC server log show the following:

To Reproduce Steps to reproduce the behavior:

1. Clone repository

export GIT_ACCOUNT=senzing
export GIT_REPOSITORY=docker-compose-demo
export GIT_ACCOUNT_DIR=~/${GIT_ACCOUNT}.git
export GIT_REPOSITORY_DIR="${GIT_ACCOUNT_DIR}/${GIT_REPOSITORY}"
export GIT_REPOSITORY_URL="https://github.com/${GIT_ACCOUNT}/${GIT_REPOSITORY}.git"
mkdir --parents ${GIT_ACCOUNT_DIR}
cd  ${GIT_ACCOUNT_DIR}
git clone  --recurse-submodules ${GIT_REPOSITORY_URL}

2. Checkout branch.

cd ${GIT_REPOSITORY_DIR}
git checkout issue-211.dockter.1

3. Bring up docker-compose formation. https://github.com/Senzing/docker-compose-demo/blob/master/docs/docker-compose-rabbitmq-postgresql/README.md
4. Load data. In Entity Search Web App, localhost:8251:
   1. menu > Admin > Load Data
      1. Note: At this point "Error Encountered" is seen.
   2. Chose .../g2/python/demo/sample/sample_company.json
      1. "Http failure response for http://localhost:8251/api/bulk-data/analyze: 500 Server Error " is seen.

This had to do with sending JSON-lines formatted data while specifying a content-type of application/json.

I don't think that there is anything for @Ara or myself to address in this. Reassigning to @docktermj and you can close if you agree or assign back to one of us with a counter-argument.
