Export - One reconciliation causing export error

I am getting this error when I try to export:

I narrowed it down to the specific reconciliation in our workflow that is causing the issue but I do not know why it is happening or how to fix it. The reconciliation looks good in Silverfin and I am not getting any errors in the code.

Dear @tdcurrie,

Thank you for your question.

Would it be possible to send your question to Silverfin Helpdesk (support@getsilverfin.com), so that this issue can be investigated further?

Kind regards,

Irina
