Hello,

I keep on hitting the same errors:

"API call to dfareporting.placements.insert failed with error: 11022 : Placement start date must be before or same as end date."

Here are the logs from the executions in AppScript:

Placement Body for row 2: { "name": "IN25789012_2025W48_LittleLions-20250002_Awa_OpenWeb_BHV_300x600_DBIG_FR-Topic-Custom", "campaignId": 34537951, "siteId": 4097858, "advertiserId": "10807808", "size": { "width": 300, "height": 600 }, "compatibility": "DISPLAY", "startDate": "2025-11-18", "endDate": "2025-12-31", "paymentSource": "PLACEMENT_AGENCY_PAID", "pricing": { "pricingType": "PRICING_TYPE_CPM", "rate": 10, "units": 1000, "startDate": "2025-11-18", "endDate": "2025-12-31" }, "tagFormats": [ "PLACEMENT_TAG_STANDARD" ] }

The dates are correct and also within the range of the campaign. So I don't understand while I keep getting that error.
