I'm having a problem on a 8.5.0 site that is in development. The search in the File manager has seemed to be very buggy/unreliable since the start of the content population. As things stand I cannot access the file manager at all now due to an Exception. It happened after running a search for a specific word.

This is the error I am getting - I was searching for the term 'Donovan':

Doctrine \ DBAL \ Exception \ InvalidFieldNameException
An exception occurred while executing 'SELECT f.fID, fv.fvDateAdded FROM Files f INNER JOIN FileVersions fv ON f.fID = fv.fID and fv.fvIsApproved = 1 LEFT JOIN FileSearchIndexAttributes fsi ON f.fID = fsi.fID LEFT JOIN Users u ON f.uID = u.uID WHERE (fv.fvFilename LIKE ?)

I have tried rebooting the server, and Refreshing Database Entities (ie here: mysite.com/index.php/dashboard/system/environment/entities/view) but that hasn't helped.

Has anyone experienced this or have any suggestions?

Thanks.
