Unable to create job in sandbox if one was created <10s ago

Bug Reporting

Our Stuart integration tests started breaking a few days ago. After digging in, what appears to be happening is new jobs can no longer be created within ~10 seconds of each other. To reproduce, use the example payload provided in the job creation API docs (excluding the pickup_at field):

{
    "job": {
        "pickups": [
            {
                "address": "32 Coombe Ln, Raynes Park, London SW20 0LA",
                "comment": "Ask Bobby",
                "contact": {
                    "firstname": "Bobby",
                    "lastname": "Brown",
                    "phone": "+33610101010",
                    "email": "bobby.brown@pizzashop.com",
                    "company": "Pizza Shop"
                }
            }
        ],
        "dropoffs": [
            {
                "package_type": "medium",
                "package_description": "yellow package",
                "client_reference": "[your_client_ref]",
                "address": "23 Ethelbert Rd, London SW20 8QD",
                "comment": "3rd floor on the right",
                "end_customer_time_window_start": "2021-12-12T11:00:00.000+02:00",
                "end_customer_time_window_end": "2021-12-12T13:00:00.000+02:00",
                "contact": {
                    "firstname": "Julia",
                    "lastname": "Moore",
                    "phone": "+33712222222",
                    "email": "client3@email.com",
                    "company": "Sample Company Inc."
                }
            }
        ]
    }
}

This should succeed. Then make another job creation request within a few seconds of the first (but with a new client_reference).

This will fail with a 500 and the following payload:

{
    "error": "UNKNOWN",
    "message": "Something went wrong. Please try again later."
}

If you keep retrying, about 10 seconds later the request will eventually succeed.

The regression occurred some time between 2025-08-13T23:45:00Z and 2025-08-14T16:24:00Z, and has been in effect ever since.

Thanks in advance!

Hi Mirek,

I tested creating test jobs using the same payload as you (from the logs), less than a second apart, and updated the client reference — it worked without any issues.

Could you please make sure to change the client reference each time? Also, let me know if you still encounter the error. If so, could you share a full job payload sample with me?

Thanks!
Tasnim

Hi Mirek

I found that our Sandbox has been experiencing some bugs since August 14th, which caused the error message “Something went wrong. Please try again later.”
This issue was resolved this morning, so you shouldn’t encounter these errors anymore.

Sorry for the inconvenience, and thank you for your patience.

Best,
Tasnim
