Dear all, Thanks for your kind reply. Due to I access the internet via proxy, I have solved that by: setings->open proxy settings->LAN settings->check: Bypass proxy server for local address.
Right that makes sense. I should not be reporting that as an error. I patch Zotero.ItemTreeView.prototype.getCellText so I can display the citekey, but that is being called well before Zotero.Schema.schemaUpdatePromise resolves so well before the BBT db is ready. The error is harmless - the method returns an empty string when the bbt db isn't ready.
For others, see Troubleshooting Translator Errors.
