Error on exporting invoices

Hi Tuan

I have recently updated all my sites to PHP 8.
I am tyring to export EB invoices by month and some of them are exporting OK and some are returning the error 

0 property_exists(): Argument #1 ($object_or_class) must be of type object|string, null given

 Return to Dashboard

Do you have any idea how to fix this?

I am running  J4.2.2  EB 4.2.1  PHP8.0

Thanks
Alison

Hi Alison

I guess I will need to check it directly on your site to see what's wrong. Please submit a support ticket sending me super admin account of your site so that I can check it

Regards,

Tuan
