error when trying to export a space: column backuprest0_.cancel_time does not exist

Hi all -

I'm trying to export a space from Confluence Server 8.4.5, and it invariably comes back with an error, amounting to a missing column in some database table. Here is the relevant extract from the log:

...

Any ideas how to fix this? Even knowing what table to look at in the database might be helpful.

Hi @Emmanouil Lazarides ,

it seems an issue at db level. Could you share DBMS and collation?
