Import Scheme rule "If object is not found" = "Treat as Error" is ignored (PriceHistory import)

Bug: Import Scheme rule "If object is not found" = Treat as Error is ignored (PriceHistory import)

Summary

In Simple Entity Import Scheme Manager (v2), setting Import Rules → If object is not found = Treat as Error does not prevent booking.
When an object referenced by an input field is missing (e.g., Pricing Policy), the import still succeeds and the item is booked using a default value.

You can see the setting in com.finmars.standard-import-from-file:instruments.pricehistory:prices_prc:

---

Environment

• PMS Core: latest
• Import scheme user code: com.finmars.standard-import-from-file:instruments.pricehistory:prices_prc
• UI: Simple Entity Import Scheme Manager (v2)

---

Steps to Reproduce

1. Install latest PMS Core
2. Open Import → Import Data from File
3. Select entity
   Price History
4. Select Import Scheme
   STD - PRC
5. Import a row with a non-existing Pricing Policy:

[
    {
        "Accrued Price": 0,
        "Date": "2011-08-05T00:00:00",
        "Factor": 1,
        "Instrument ID": "-",
        "Modified Duration": 0,
        "Pricing Policy": "com.finmars.standard-pricing:doesnt_exist",
        "Principal Price": 1,
        "YTM": 0,
        "is_temporary_price": false,
        "long_delta": 0,
        "short_delta": 0
    }
]

---

Actual Result

• "com.finmars.standard-pricing:doesnt_exist" is not found
• Key pricing_policy is removed from final_inputs
• Error message is formed:
  None Relation model error: KeyError('pricing_policy')
• Import finishes with status: "success"
• Price is booked (default pricing policy is applied)

Example response:

{
  "error_message": "None Relation model error: KeyError('pricing_policy')",
  "final_inputs": {
    "accrued_price": 0,
    "date": "2011-08-05",
    "factor": 1,
    "instrument": "-",
    "principal_price": 1
  },
  "message": "Item Imported pricehistory",
  "status": "success"
}

---

Expected Result

• "com.finmars.standard-pricing:doesnt_exist" is not found
• Key pricing_policy is removed from final_inputs
• Error message is formed
• Import result must be status: "error"
• Price must NOT be booked

---

Notes

It appears that when a referenced relation is not found:

• the field is removed from final_inputs
• an error message is generated
• but the pipeline continues and applies defaults

The "Treat as Error" rule does not escalate the failure to an error status and does not stop booking.
