InsecureRequestWarning while running examples

[pranaythales]

Hello,

When I run the command sudo docker-compose up --build in examples to start the receiver and transmitter (without doing any changes to the pulled code), I continuously get InsecureRequestWarning like the one shown below:

> examples-receiver-1     | /usr/local/lib/python3.9/site-packages/urllib3/connectionpool.py:1045: InsecureRequestWarning: Unverified HTTPS request is being made to host 'transmitter'. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/1.26.x/advanced-usage.html#ssl-warnings

I am not sure if this is an issue or not, but the example doesn't seem to work, hence I'm asking this. Can someone please provide the detail steps or pre-requisites to run the example as I am a bit lost here. I just want to run a sample transmitter and receiver and make them communicate with each other according to the SSE spec

My current steps were:

1. cloning the repository
2. Ru the command sudo docker-compose up --build inside the examples directory
3. Open the https://localhost/ui in the browser and http://localhost:5003/request_verification in the browser where it shows that it has "Submitted request for verification event". but the output in the terminal looks like this:
