strip_trailing_whitespace_from_messages

def strip_trailing_whitespace_from_messages(messages: List[OpenAIMessage]):
Strip trailing whitespace from all message contents in a list of messages. This is necessary because the Anthropic API doesn’t allow trailing whitespace in message content. Parameters:
  • messages (List[OpenAIMessage]): List of messages to process
Returns: List[OpenAIMessage]: The processed messages with trailing whitespace removed
