Auto-export stops working, "Error: translation failed"

Support log ID: D3UP2CF5-euc

Exporter used: Better BibLaTex and Better CSL JSON

BBT 5.2.48 Zotero 5.0.96.3

Over the last couple of days, I have recurrently observed that BBT stops auto-exporting my library to both Better CSL JSON or Better BibLaTex a while after setting up the auto-export, giving “Error: Translation failed” in the Preferences BBT panel.

I do not get any error messages: The progress bar for BBT export shows normally (somewhat slow), but eventually fills up and disappears (“Status: done” in Preferences). However, the export bib- or json-file remains unchanged. (I noticed this because new entries added in Zotero were not available to the Citations plugin I use in Obsidian, which relies on the BBT export.)

When I remove and re-install BBT and set up the auto-export anew, it will again work for a while but then stop working as described above. In the meantime, I will have added new entries to Zotero and manually changed citekeys. Some of these are exported as expected, I cannot pin down when export begins to fail. I personally cannot relate export failure to any specific use case.

Any help or pointers would be greatly appreciated – as is your committed work on this great plugin!

PS: Unsure about #7 and #8 of the support request requirements – my export problem does not relate to a specific reference and I do not have a problem with wrong export outputs.
