[Bug]: Langfuse integration: error generated in logging handler - dictionary changed size during iteration

[ngamolsky]

What happened?

I get errors generated from the langfuse logging handler.

This is very similar to fixed issue here: #2245

I believe we just need to remove the response obj if we are to follow the same pattern.

Relevant log output
