When I tried it yesterday and again today, with From and Until as above, Update Metadata Index generated the empty error:
The metadata index could not be updated. The following error(s) occurred:
below which there's nothing. Looking in the HTML source, it reads:
<p>The metadata index could not be updated. The following error(s) occurred:</p>
The only way I can force the 'update' is to put a long ago date into From and today's date into Until, when of course it then reharvests all records, which is time-consuming. What's causing the empty error, can anyone tell me? More importantly, how can I fix it? As far as I know there hasn't been any config change to the repository software on the server, though I don't know for sure as I'm not the server admin. I've not made any config changes to the Harvester admin setup. What concerns me is that, eventually, we're going to automate harvesting via a scheduled job to run the update via the command line, and if this blank error occurs we many never know it's happening and our archive will go increasingly out of date.
TIA for any tips/suggestions.
