How to resolve 'curl: option --data-raw: is unknown' error

Question

I am trying to run shell script with a curl command as below with --data-raw as body.

curl --location --request POST '<URL>' \
  --header 'Content-Type: application/json' \
  --data-raw '{
"blocks": [
  {
 "type": "header",
 "text": {
  "type": "plain_text",
  "text": "Help Text",
  "emoji": true
 }
},
{
 "type": "divider"
},
]
}'

Output:

curl: option --data-raw: is unknown
curl: try 'curl --help' or 'curl --manual' for more information

I couldn't find any error with the json validator. Please suggest a solution. TIA.

Answer 1

Here, you have 2 issue.

• your JSON is invalid, the , line 14 need to be removed
• use --data and a heredoc :

curl --location --request POST '<URL>' \
  --header 'Content-Type: application/json' \
  --data "@/dev/stdin"<<EOF
{
  "blocks": [
    {
      "type": "header",
      "text": {
        "type": "plain_text",
        "text": "Help Text",
        "emoji": true
      }
    },
    {
      "type": "divider"
    }
  ]
}
EOF

Here documents:

cat <<EOF followed by several lines of text, followed by the literal string EOF on a new line, NOT indented. The portion between the EOFs is passed to the command as standard input. If 'EOF' is 'quoted', substitutions WON'T be done; otherwise they are. See <<- for the indented variety (not recommended, need TABs).
