Docker fetch not working

Describe the bug
I build and ran the Dockerfile in src/fetch and ran the container

docker run -it fetch-server

It's working fine but not able to initilize and response back!

To Reproduce
Steps to reproduce the behavior:

1. docker run -it fetch-server
2. Open the terminal/exec inside the container
3. send the following to STDIN printf '{"jsonrpc":"2.0","method":"initialize","params":{"protocolVersion":"1.0","capabilities":{},"clientInfo":{"name":"test","version":"1"}},"id":"1"}\n{"jsonrpc":"2.0","method":"tools/call","params":{"name":"fetch","arguments":{"url":"https://www.google.com","max_length":5000,"raw":true}},"id":"fetch_google"}\n' > /proc/1/fd/0
4. View the logs
5. It's not working and through the exception

Expected behavior
Should return the list of tools, and page fetch

  Additional context
  Add any other context about the problem here.

Start with the Dockerfile in src/fetch and reproduce the reported docker run and STDIN commands. Inspect the initialization and request sequence around the logged exception; the issue is done when initialization completes and the fetch tool returns the requested page without an exception.
