Common Errors

​
401 Unauthorized

Cause: Missing or invalid API key 
{
  "detail": "Invalid API key",
  "code": "INVALID_API_KEY"
}
Solution: Verify your API key is valid and active. Get a new one from Settings → API.

​
404 Not Found

Cause: Organization not found or invalid UUID reference 
{
  "code": "ORGANIZATION_NOT_FOUND",
  "detail": "Organization with id=UUID('...') not found"
}
Solution: Verify that the x-organization-id header contains a valid organization UUID, and that the unknown_vehicle_id and vehicle_fuel_id are valid.

​
422 Validation Error

Cause: Missing required parameters or invalid values 
{
  "detail": [
    {
      "loc": ["body", "vehicle_fuel_id"],
      "msg": "Either vehicle_fuel_id or custom_emission_factor_id must be provided",
      "type": "value_error"
    }
  ]
}
Solution: Ensure all required fields are provided. Either vehicle_fuel_id or custom_emission_factor_id must be specified. Country code should be 2-3 characters.
