Message

Time range is malformed. Both from and to must be ISO 8601 strings (e.g. 2026-05-11T00:00:00Z) and to must be later than from.

Common cause

  • Sent a Unix timestamp instead of ISO 8601.
  • Used a date without a time (2026-05-11 instead of 2026-05-11T00:00:00Z).
  • Forgot the Z suffix (we require explicit UTC).
  • Swapped from/to so to < from.

Fix

Use canonical ISO 8601 UTC with the Z suffix:
2026-05-11T00:00:00Z
In Python:
from datetime import datetime, timezone
now = datetime.now(timezone.utc).strftime("%Y-%m-%dT%H:%M:%SZ")
In JavaScript:
new Date().toISOString();
Both already emit the Z suffix.
