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

2026-05-11T00:00:00Z

from datetime import datetime, timezone
now = datetime.now(timezone.utc).strftime("%Y-%m-%dT%H:%M:%SZ")

new Date().toISOString();
