seed-missing
The request names no seed.
- Status:
400 Bad Request - Route:
POST /api/v1/generate-events - Description:
seed is missing: expected 1 to 64 of a-z, 0-9, and - - Details: Empty.
Why It Happens#
The body has no field seed, or its value is null. The seed is mandatory and has no default, since it decides which data set you get (see The Seed).
How to Fix It#
Add the field seed, with 1 to 64 characters of a to z, 0 to 9, and -. Choose one that says what the data set is for:
"seed": "ddd-workshop-2026"
The standard data sets of the product page use the seed standard; with it, and with the domain, scenario, range, and event count of one of them, you get that very data set.
