TL;DR

Resizing images to be within the 2000px dimension limit before sending them with a prompt may resolve the error.

Guidance

• Verify the dimensions of the images being sent to ensure they are not exceeding the 2000px limit.
• Consider implementing an image processing step to resize images before sending them, as suggested in the bug description.
• Review the error messages to identify which specific image is causing the issue, focusing on the "messages.108.content.3.image.source.base64.data" part of the error message.
• Check if there are any configuration options or settings that can be adjusted to increase the image dimension limit, although this is not directly implied in the provided information.

Example

No specific code example can be provided without more context on the image processing library or framework being used. However, the general approach would involve checking the image dimensions and resizing them if necessary before making the request.

Notes

The provided solution assumes that resizing the images will resolve the issue. If the error persists after resizing, further investigation into the request and the API's handling of images may be necessary.

Recommendation

Apply a workaround by resizing images before sending them, as directly increasing the dimension limit is not mentioned as an option in the provided information. This approach addresses the immediate issue of image size limits for many-image requests.
