How to fix this issue

Your dataset is missing the start-date column.

The Conservation area guidance explains how to fix the issue:

start-date

The date the validity of the record starts, written in YYYY-MM-DD format. Usually, this will be the same as the designation date. If anything about the conservation area has changed, for example, the boundary, it should be the date of that change.

Example:

1984-04-25

With dates, some data is better than no data, so:

1984 is fine
1984-04 is better
1984-04-25 is brilliant
