Issue with Handling Images Received from WhatsApp Business API

[giovanni.coco]

Hi there,

I’m currently facing an issue while handling images received from the WhatsApp Business API in Pipedream. When I receive an image message, WhatsApp indicates that the MIME type is “image/jpeg”. However, when I try to access this image in Pipedream, I’m encountering errors.

Here’s a brief overview of the problem:

• WhatsApp indicates that the MIME type of the received image is “image/jpeg”.
• Upon receiving the image in Pipedream, I’m getting binary data in the return_value.
• I’ve tried saving this binary data to the /tmp folder, but when I upload the image to S3 and attempt to download it, the image does not open. It seems to be corrupted or improperly encoded.

I’ve tried a few different approaches, including converting the binary data to base64 before saving it, but the issue persists.

Could you please provide guidance on how to properly handle images received from the WhatsApp Business API in Pipedream? Specifically, I’m looking for assistance with:

1. Correctly interpreting and handling the binary data received from WhatsApp.
2. Ensuring that the image data is properly encoded and saved so that it can be successfully uploaded to S3 and downloaded without any issues.

Any insights or suggestions you could provide to help resolve this issue would be greatly appreciated.

Thank you very much for your assistance!

Hi @giovanni.coco,

Handling binary data, especially images received from an API like WhatsApp Business API, and ensuring their integrity when saving or transferring them, can be challenging. Based on your description, it seems like the issue might be related to how the binary data is being handled or encoded in Pipedream before uploading to S3. Here’s a step-by-step guide on how you can handle and save images received from the WhatsApp Business API in Pipedream, ensuring they are properly encoded for successful upload to S3 and download:

1. Correctly interpreting and handling the binary data received from WhatsApp:

When you receive an image (binary data) in Pipedream from the WhatsApp Business API, it’s crucial to handle this data correctly to avoid corruption. Since you’re receiving binary data in the return_value, you should ensure that this data is correctly interpreted as binary data in your Pipedream workflow.

2. Saving the binary data to the /tmp directory correctly:

To save the binary data to the /tmp directory without corrupting it, you should write the data directly as binary. Here’s how you can do it in a Pipedream Node.js code step:

import { writeFile } from "fs/promises";

export default defineComponent({
  async run({ steps, $ }) {
    // Assuming `binaryData` is the binary data you received from WhatsApp
    const binaryData = steps.previous_step.return_value;
    
    // Specify the path in the /tmp directory
    const filePath = `/tmp/image.jpeg`;

    // Write the binary data directly to a file
    await writeFile(filePath, binaryData, 'binary');

    // Now you can proceed to upload the file to S3 or perform other actions
  },
});

3. Uploading the image to S3:

After saving the image to the /tmp directory, you can use the AWS SDK or a Pipedream pre-built action to upload the file to S3. Ensure you’re setting the correct ContentType (image/jpeg in your case) when uploading to S3 to avoid issues when downloading the image.

4. Verifying the integrity of the image:

After uploading the image to S3, you can download it to verify its integrity. If the image opens correctly, it means the binary data was handled and encoded properly throughout the process.

If you continue to face issues, it might be helpful to inspect the binary data you’re

Thanks Pi. But has the same issue. The problem is how Pipedream is handling with image since WhatsApp provided image/jpeg type.
