'Add Serial No' picking does not show list

Hi,

Anyone has this experiance? When on a Delivery Note for serial item, clicking the “Add Serial No” button does not bring up the picking list. I have the selected wharehouse and correct batch.

ERPNext V12.0.6

The Item is a batch and serialised item, so not sure if thats an issue?

Any assistance will be appreciated.

Kind regards
Hemant

This is the error log i see on the console.
