Error when try to change status to shipped

-- HikaShop version -- : 6.1.1

I get this error when trying to change order status from confirmed to shipped.

Hi,

Please activate the "debug system" setting of the Joomla configuration page and try again. It will display more information about the problem and that will allow us to tell you what to do.

It happens only on one order

Hi,

Thanks. I'm not able to reproduce the issue on my end and the line numbers in the call stack you provided don't match with what I have for the 6.1.1 on my end. So I'm not sure the fix I made will be what needs to be done. Download again the install package of HikaShop on our website and install it on yours. It will add the fix I made. Hopefully, that will be enough. If not, please reproduce the issue again with the debug turned on, and provide the new call stack.
