How do I construct a JSON message to send with Amazon-SES? - json

Question

I'm running into the following error when I try to send an email via Amazon-SES:
Error parsing parameter '--raw-message': Invalid JSON: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)
I don't understand where I am messing up the JSON message...
This is the bash script I am using:
echo '{\"Data\":
"Subject:'${SUBJECT}'\\n
MIME-Version: 1.0\n
Content-type: Multipart/Mixed;
boundary=\"NextPart\"\\n\\n--NextPart\\n
Content-Type: text/plain\\n\\n'${BODY}'
\\n\\n--NextPart
\\nContent-Type:'${ATTACHMENT_TYPE}';
\nContent-Disposition: attachment;
filename=\"'${ATTACHMENT_FILE_NAME}'\"\\n
\\n'$(cat ./${ATTACHMENT_FILE_TO_READ_FROM_DISK})'
\\n--NextPart--"}' > "$tmp_message"
aws ses send-raw-email --region us-east-1 --from sender#gmail.com --destination file://$tmp_destination --raw-message file://"$tmp_message"

Use jq to verify your json is fine
#! /bin/bash
echo '{\"Data\":
"Subject:'${SUBJECT}'\\n
MIME-Version: 1.0\n
Content-type: Multipart/Mixed;
boundary=\"NextPart\"\\n\\n--NextPart\\n
Content-Type: text/plain\\n\\n'${BODY}'
\\n\\n--NextPart
\\nContent-Type:'${ATTACHMENT_TYPE}';
\nContent-Disposition: attachment;
filename=\"'${ATTACHMENT_FILE_NAME}'\"\\n
\\n'$(cat ./${ATTACHMENT_FILE_TO_READ_FROM_DISK})'
\\n--NextPart--"}' > "$tmp_message"
if jq < "$tmp_message"; then
aws ses send-raw-email --region us-east-1 --from sender#gmail.com --destination file://"$tmp_destination" --raw-message file://"$tmp_message"
else
echo "ERROR" >&2
