0005·Date is not in a valid format
Invoice headerOccasional
What this means
The date arrived in a shape FBR cannot parse. It expects year, month, day, hyphen-separated, with no time component.
Why it happens
- A locale format was used, typically day-first.
- Month names were spelled out.
- A timestamp was submitted where a date was expected.
How to fix it
- 1Format dates explicitly rather than relying on default serialisation.
- 2Strip any time component before submission.
How Ordyoo handles this
Dates are stored as calendar dates rather than timestamps, so there is no time component to leak.
