Session State Persistence Failure in FastMCP's Streamable-HTTP Implementation( please help :c )

[LazySeaSeal]

The MCP-Atlassian server successfully initializes sessions and authenticates, but loses session state between HTTP requests. Even after receiving session IDs and initializing, the server responds as if initialization hasn't completed. Server logs confirm this is a session persistence issue in FastMCP’s streamable-http backend.
