Context Window Overflow Error in Strands Agent

Error Description

When running the Strands agent, I'm encountering a context window overflow error followed by a recursion error.

Error Details

The primary error is a ContextWindowOverflowException with the following details:

input length and `max_tokens` exceed context limit: 142422 + 64000 > 204658

This indicates that the total tokens (input + max_tokens) exceeds the model's context window limit of 204,658 tokens.

Full Error Trace

Traceback (most recent call last):
  # ... [previous trace details]
  
strands.types.exceptions.ContextWindowOverflowException: An error occurred (validationException) when calling the ConverseStream operation: The model returned the following errors: input length and `max_tokens` exceed context limit: 142422 + 64000 > 204658, decrease input length or `max_tokens` and try again

This is followed by a recursion error while handling the initial exception:

RecursionError: maximum recursion depth exceeded

Environment Details

• Python version: 3.10
• Package: Strands
• Running in virtual environment

Question

Has anyone encountered this issue and found a solution? I'm particularly interested in best practices for handling large inputs with the Strands agent.

Please let me know if you need any additional information or clarification.
