When does this happen?

IF Tool call definitions are not translated to proper parameters in Bedrock requests when using Claude 4.5 Sonnet.

How others solved it

THEN Update LiteLLM to version 1.78.5 or later to ensure tool definitions are correctly passed to the Bedrock API for Claude 4.5 Sonnet models. If using an older version, tool calls will be silently omitted.
