If you are using AWS SES your payload has two issues, first your boundary is different, and second just keep in mind the line breaks, your string template should be like this:

var payload = `From: 'Amarjeet Singh' <${sender}>
To: ${recipient}
Subject: AWS SES Attachment
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary=7f1a313ee430f85a8b054f085ae67abd6ee9c52aa8d056e7f7e19c6e2887

--7f1a313ee430f85a8b054f085ae67abd6ee9c52aa8d056e7f7e19c6e2887
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

This is the <b>body</b> of the email.

--7f1a313ee430f85a8b054f085ae67abd6ee9c52aa8d056e7f7e19c6e2887
Content-Type: application/json; charset=UTF-8; 
Content-Disposition: attachment; filename="colors.json"
Content-Transfer-Encoding: base64

${file}
--7f1a313ee430f85a8b054f085ae67abd6ee9c52aa8d056e7f7e19c6e2887--`;
