Invalid run_at timestamp: {e}

Error message

Invalid run_at timestamp: {e}

What it means

When creating an agent job with a 'run_at' one-shot time, the raw string is parsed with DateTime::parse_from_rfc3339; this fires when it is not RFC 3339 (missing timezone, wrong separator, relative phrases like 'tomorrow'). Nothing is scheduled.

Solutions

1. Pass run_at as an RFC 3339 timestamp, e.g. 2026-09-03T09:00:00Z
2. Use the 'delay' (duration) parameter instead for relative times
