The followign is the request

@test "Test 1" {

    sleep 5s
    
 
    TEST_URL_HTTP="http://10.15.33.230:8080/service/v1/lb"
    RESPONSE=""
    for x in {0..20} ;
    do
        echo "Sending request to $TEST_URL_HTTP"

        RESPONSE=$(curl --connect-timeout 1 -s -f -X POST  -H 'Content-Type: application/json' -d '@./folder/request.json' $TEST_URL_HTTP) && break
        sleep 5
    done
    
    if [ $x -lt 20 ] ;
    then
        echo "Received echo response"
    else
        echo "Failed to get echo response"
        exit 1
    fi
    
}
