Re: [basex-talk] Error report in baseX-dev

Hi Jack,

Does the problem persist if you restart the BaseX server instance? If yes, could you check if there’s n upd.basex file in the corresponding database directory (dboe-xml) [1]?

The uploading process originally stopped and gave an error message and listed about 4 files that would not be included in upload but the rest appeared but now nothing else can be added or deleted.

Do you know why the process stopped? Was the problem caused by oXygen, your network, of BaseX (did you get an error message)?

Sorry for all the questions ;) Christian

Hi,

I’m trying to delete some files that I just added to my db

To give context, I originally added them via Oxygen data source explorer baseXdev, but I am trying to delete them in the dba https://basex-dev.eos.arz.oeaw.ac.at/dba/database?name=dboe-xml and the error 500 message below is what occurs.
