Trouble shooting when processing document into knowledgebase

Hi,

I created and published a knowledge pipeline. After I uploaded a PDF file and processed it.

It is with “a document indexed failed” status. I find below error.

Instance <Document at 0x7ebf6cfa9e20> is not bound to a Session; attribute refresh operation cannot proceed (Background on this error at: Error Messages — SQLAlchemy 2.0 Documentation )

Is anyone faced similar issue? Thanks.

ZB

The issued is fixed after upgrading below components to 1.9.2.
