Hey @shahidcodes, sorry I've been super busy lately, will try to check this out over the next few days!

Hi @shahidcodes, I'm not able to reproduce your issue since it seems to be coming from some external document (based on your error message, I assume you have an array of InvoiceDocument on another schema, this seems to be causing the problem). Can you provide a more complete example of the issue?

Hi @francescov1 , Initially as a workaround I removed the InvoiceModel from mongoose.model call but now I am trying to reproduce it seems fine. Thanks for the support and sorry for late reply
