Serialization error

[1719pankaj]

Description of the bug:

Whenever I try to ask coding questions ("write fizzbuzz in python", "implement fizzbuzz in java") it gives the below error and crashes.
Any other question asked works fine.

Actual vs expected behavior:

model: gemini-2.0-flash-exp
sdk version: 0.9

Any other information you'd like to share?
