Unmatched close brace/bracket-CodePudding

I'm trying to execute an script in bash, but throw me this error,

curl: (3) URL using bad/illegal format or missing URL
curl: (3) URL using bad/illegal format or missing URL
curl: (3) URL using bad/illegal format or missing URL
curl: (3) unmatched close brace/bracket in URL position 24:
UTC","user_id":"01234"}}

i tried removing the braces but does not work, this is the line,

response=$(curl  -X POST -H "Authorization: Bearer ${bearer_token}" -H "Content-Type: application/json" -d '{"cursus_user":{"begin_at":"'${start}'","cursus_id":"'${cursus_id}'","end_at":"'${end}'","user_id":"'${user}'"}}' "https://xxxxxx/xxxxxx.com")

Anyone know where is the issue?, i'm stuck, thanks in advance.

[ UPDATE ]

Really i can't see the error :(

'
{
    "cursus_user":
    {
        "begin_at":     "'${start}'",
        "cursus_id":    "'${cursus_id}'",
        "end_at":       "'${end}'",
        "user_id":      "'${user}'"
    }
}

This is really more of a formatted comment.

Two tips:

use jq to generate JSON -- it will get all the quoting correct for you
use arrays for readability (I dislike scrolling horizontally)

data=$(
    jq  --null-input \
        --compact-output \
        --arg begin_at  "$start" \
        --arg cursus_id "$cursus_id" \
        --arg end_at    "$end" \
        --arg user_id   "$user" \
        '{cursus_user: $ARGS.named}'
)

curl_opts=(
    -X POST
    -H "Authorization: Bearer ${bearer_token}"
    -H "Content-Type: application/json" 
    -d "$data"
)

response=$(curl "${curl_opts[@]}" "https://xxxxxx/xxxxxx.com")

Shellcheck identifies several unquoted variables in the curl command. It even provides the corrected code:

response=$(curl -X POST -H "Authorization: Bearer ${bearer_token}" -H "Content-Type: application/json" -d '{"cursus_user":{"begin_at":"'"${start}"'","cursus_id":"'"${cursus_id}"'","end_at":"'"${end}"'","user_id":"'"${user}"'"}}' "https://xxxxxx/xxxxxx.com")

Using Shellcheck often saves a lot of time when working with shell code.
