…cs#1454) Bedrock rejects `null` for optional fields like `ToolUseBlock.caller` that the Anthropic API silently ignores. When users roundtrip a ToolUseBlock (with `caller: None`) back into a subsequent request, the Bedrock API returns a 400 error. Strip None values from message content block dicts in `_prepare_options` before the request is sent. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

_strip_none_valueshelper and applies it to message content block dicts in the Bedrock_prepare_optionsfunction, removingNonevalues before the request is sent.Verification
