DALLE Image Generation Format Mismatch Error

[BlakeRhodes]

What happened?

Description

When attempting to generate an image using the DALLE function, the system displays an error message about a format mismatch, but the image actually displays successfully. The specific error is:

An error occurred while processing the request: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.11.content.3.image.source.base64.data: Image does not match the provided media type image/jpeg"}}

Environment

• LibreChat version: v0.7.7
• Browser: Chrome 134.0.6998.165
• Operating System: PopOs

Steps to Reproduce

1. Engage with the AI assistant
2. Ask the assistant to generate an image using DALLE
3. When the assistant attempts to generate the image, the error appears despite the image showing up correctly

Expected Behavior

The image should generate without showing an error message.

Actual Behavior

The image appears to generate and display successfully, but an error message is shown suggesting a format mismatch. The error specifically mentions that the image doesn't match the expected media type (image/jpeg).

Error Message

Something went wrong. Here's the specific error message we encountered: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.11.content.3.image.source.base64.data: Image does not match the provided media type image/jpeg"}}

Additional Context

The error seems to be happening because the system is expecting a JPEG format, but the image might be in a different format (possibly PNG). Despite the error, the functionality works as the image is displayed to the user. This appears to be a backend issue with how LibreChat is handling the DALLE image generation response.
