Unable to send curl output to discord using webhook which is otherwise printing it in my bash terminal - bash

Question

status=$(curl -i -s -H "Authorization: token abc123" https://www.some_url.com | awk 'NR==18')
if [ "$status" != 200 ]; then
echo "$status"
fi
The above code is working and echo is printing the output in my console.
But when I use discord webhook, it doesn't send message there and throws following error: {"code": 50109, "message": "The request body contains invalid JSON."}
webhook=https://discord.com/api/webhooks/abc123
status=$(curl -i -s -H "Authorization: token abc123" https://www.some_url.com | awk 'NR==18')
if [ "$status" != 200 ]; then
curl -H "Content-Type: application/json" -X POST -d '{"content":"'"$status"'"}' $webhook
fi
I can send a normal message through webhook but not this curl output. The output is suppose to be HTML error message.
Even if I change awk 'NR==18' to awk 'NR==1', it's not sending even the one line output which is suppose to be something like: HTTP/1.1 401 Unauthorized

I have a discord bot (webhook) running on a raspberry pi from a bash script, so I think it is the same thing you are looking for
sendcontent='{"username": "Botname", "content": "'"${messagearray[#]}"'"}'
curl -H "Content-Type: application/json" -d "$sendcontent" "$webhookurl"
I would suggest the following change to your code:
messagearray=($(curl -i -s -H "Authorization: token abc123" https://www.some_url.com | awk 'NR==18'))
EDIT:
It seems that there are nasty invisible characters in the curl+awk command return, therefore the above solution needs to be modified as below
(This bash file test with the provided url from comments)
#!/bin/bash
webhookurl="https://mywebhook"
messagearray=($(curl -i -s https://www.google.com/ | awk 'NR==1'))
#this next line removes nasty characters that give json errors (keeps only letters, numbers SPACE and -)
message=`echo ${messagearray[#]} | sed 's/[^0-9A-Za-z -]*//g'`;
sendcontent='{"username": "Botname", "content": "'"$message"'"}'
curl -H "Content-Type: application/json" -d "$sendcontent" "$webhookurl"
This successfully sends HTTP/2 200 in discord
