When does this happen?
IF When using Claude 3.7 Sonnet with computer_20250124 tool on Bedrock via LiteLLM, a 400 Bad Request error occurs with message: 'Input tag 'computer_20250124' found using 'type' does not match any of the expected tags'.
How others solved it
THEN Ensure the anthropic_beta header matches the tool version. For computer_20250124, use 'computer-use-2025-01-24' instead of the default 'computer-use-2024-10-22'. This may require a code change in the LiteLLM configuration or passing the correct header in additionalModelRequestFields.
