Sorry, something went wrong.
All images sent via the Baileys integration are now pre-processed and converted to JPEG format using the `sharp` library. This ensures better compatibility and prevents potential issues with unsupported formats. - Images from URLs are now downloaded via axios before processing, which allows for the use of a proxy. - The default filename and mimetype are updated to `image.jpg` and `image/jpeg` to reflect the conversion.

Reviewer's GuideIntroduces an image preprocessing pipeline in the Baileys WhatsApp service: images are downloaded or decoded, converted to JPEG via sharp (with optional proxy support), default filename and mimetype updated to .jpg/jpeg, and the mediaInput is unified in the prepareWAMessageMedia call. Sequence diagram for image preprocessing and sending in WhatsApp Baileys integrationsequenceDiagram
participant Service as BaileysStartupService
participant Proxy as Proxy (optional)
participant Axios as axios
participant Sharp as sharp
participant WA as WhatsApp API
Service->>Axios: Download image from URL (with proxy if enabled)
Axios-->>Service: Return image buffer
Service->>Sharp: Convert image buffer to JPEG
Sharp-->>Service: Return JPEG buffer
Service->>WA: Send JPEG image with updated filename/mimetype

Network errors from axios.get are not explicitly handled.
Catch errors from axios.get to prevent unhandled promise rejections when the image URL is unreachable or returns a non-200 status.

Redundant fileName assignment logic exists below.
Consolidate the fileName assignment to a single location to improve clarity and maintain consistency.
Suggested implementation:
```typescript
mediaInput = await sharp(imageBuffer).jpeg().toBuffer();
mediaMessage.fileName ??= 'image.jpg';
mediaMessage.mimetype = 'image/jpeg';
} else {
mediaInput = isURL(mediaMessage.media)
? { url: mediaMessage.media }
: Buffer.from(mediaMessage.media, 'base64');
```
If there is another assignment to `mediaMessage.fileName` elsewhere in this function or code path, it should be removed to ensure the assignment is consolidated to this single location.
