How do I encode into a multipart/form-data the bytes of an image to add to a customer request?

Hello,

I am trying to make a google sheets that, when appropriate, creates a ticket in jira's servicedesk. To communicate with the servicedesk API I am using google's apps script.

However, I am having an issue when adding a photo to the request. The photos show as the base64 encoding string opposed to want I want (the actual image).

I suppose that I am doing the encoding wrong, or the multipart/form-data format is also wrong.

The code for creating the multipart:

 

    const boundary = 'here';

    let formData = '';

    formData += `--${boundary}`;

    formData += `Content-Disposition: form-data; name=file; filename=${input.file.getName()}`;

    formData += `Content-Type: ${input.file.getContentType()}`;

    formData += Utilities.base64Encode(input.file.getBytes()) + '';

    formData += `--${boundary}--`;

The result:

This resulting file has the PNG format like the original.
