When I try to download anything from the item exchange i get this error.

Unexpected Runtime Error Something went wrong: Cannot insert the value NULL into column 'VisitorIdentifierID', table 'ItemExchange.dbo.Downloads'; column does not allow nulls. INSERT fails.

I have tried different browsers, I have tried both my linux and windows 11 operating systems, I have also tried a public librarty computer. I got the same error each time.

It should be fixed now. Sorry for the inconvenience.
