This was almost certainly caused by the disk space problems we were having recently (that are fixed now, yay! ). It's likely the SQLite scraper database got corrupted during one of these incidents. This should never happen and we're sorry about that.
I've downloaded a copy of the corrupt database and attempted a recovery with some handy steps I found. I've then copied this database back up to your scraper @chris48s. Can you please check to see if this is OK?
If it's not OK then we'll need to restore your scraper data from backup. Looking at the scraper history we probably need to restore it from the last time the scraper ran successfully, the 13th of December. Please let us know if you'd like us to carry out this restore or if the data, as recovered above, is OK.
