How to access individual items from Airtable array field containing image URLs

I’m working with the Airtable API and trying to extract image URLs from an attachment field. When I fetch regular text fields, everything works fine:

processRecords(function handlePage(entries, getNext) {
    entries.forEach(function(entry) {
        console.log('Found:', entry.get('Title'));
    });
}

But when I try to get data from an image attachment field, I get an array with objects instead of direct URLs:

processRecords(function handlePage(entries, getNext) {
    entries.forEach(function(entry) {
        console.log('Image data:', entry.get('Avatar'));
    });
}

This outputs something like:

Image data (1) [{...}]
Image data (1) [{...}]

How can I access the actual URL values from these array objects? I need to extract the specific image URLs from the attachment field data.

Each attachment object contains multiple properties beyond just the URL. When you access the attachment field, you’re getting the complete file metadata structure. Try logging the first attachment object to see its full structure:

processRecords(function handlePage(entries, getNext) {
    entries.forEach(function(entry) {
        const avatarData = entry.get('Avatar');
        if (avatarData && avatarData[0]) {
            console.log('Full attachment object:', avatarData[0]);
            // Then access the URL
            console.log('Direct URL:', avatarData[0].url);
        }
    });
}

This will show you all available properties like filename, type, size, and thumbnails. The URL property gives you the direct link to the file. Make sure to handle cases where the attachment field might be empty to prevent runtime errors.

The attachment field in Airtable returns an array of objects where each object contains metadata about the file including the URL. You need to iterate through this array and access the url property of each object.

processRecords(function handlePage(entries, getNext) {
    entries.forEach(function(entry) {
        const avatarField = entry.get('Avatar');
        if (avatarField && avatarField.length > 0) {
            avatarField.forEach(function(attachment) {
                console.log('Image URL:', attachment.url);
            });
        }
    });
}

If you only need the first image URL from the attachment field, you can simplify it to entry.get('Avatar')[0].url. Always check if the field exists and has content before accessing the URL to avoid errors with empty attachment fields.
