Your request is invalid or could not be processed by the service 449 - ""

Hi, I have problem with HTTP Requests. I’m trying to make simple post, tryied manually and using “curl”.
I’m getting an error

here is sample curl that I used - it works fine with postman

curl --location 'https://www.wakacje.pl/v2/api/offerConfiguratorV2/offerVariants' \
--header 'Content-Type: application/json' \
--data '{
    "offerId": 948499,
    "departureDate": [
        "2025-10-01:2025-10-31"
    ],
    "duration": [
        "6-8"
    ],
    "adults": 2,
    "kidsAges": [],
    "service": [
        4
    ],
    "transportType": [
        1
    ],
    "departurePlace": [
        278
    ],
    "limit": 1000,
    "orderBy": "departureDate"
}'

I have no idea what is wrong

Copy and paste the node that’s making the request, preferably the workflow so we can see what’s happening.

HTTP error code 449 is from MS IIS https://http.dev/449

It’s saying your data is invalid, so there’s likely an error in your json body that you’re sending in that node.

Have you tried:
“departureDate”: [“2025-10-01”, “2025-10-31”]
