Welcome @Octo8080X

Looks like a .env issue on first glance.

Try this:

Add a .env file to the root folder with these values:

OPENAI_API_KEY=
TAVILY_API_KEY=

Get the keys from here: https://app.tavily.com/sign-in https://platform.openai.com/api-keys

Then restart docker with: docker compose up --build

May the force be with you 🙏

@ElishaKay

Thank you

I tried again according to the instructions and was able to confirm that it works.

It was very helpful.

Problem solved.
