Invalid message content: string too long. Expected a string with maximum length 1048576, but received a longer string. Reduce the string length to comply with the limit.

To fix the "Invalid 'messages.content.text': string too long" error, you need to ensure that the string length does not exceed the maximum allowed limit. Here are the steps to resolve this issue:

• Trim or truncate the text: Reduce the length of the string to be within the 1048576 character limit.

• Split the text: Break down the long text into multiple messages, each adhering to the character limit.

• Use a summarization approach: If the entire text is not necessary, consider summarizing the content to fit within the allowed length.

• Optimize the request: Review and optimize the request to minimize the amount of text being sent in a single call.

By implementing these strategies, you can ensure your requests comply with the OpenAI API's string length constraints.
