frm.doc.member not defined in erpnext/non_profit/doctype/member/member.js

[dasistwas]

Information about bug

When the webservice "get_last_membership" is called, the argument "member" is undefined. This is because the object value frm.doc.member just does not exist in the JavaScript object frm.

Solution

In erpnext/non_profit/doctype/member/member.js replace

frm.doc.member with
frm.doc.name

In v14 this issue should have been resolved. The member.js has been rewritten:

@deepeshgarg007 thank you for moving that issue. In fact, this is not a problem anymore in v14. It only affects the non-profit module of erpnext v13. So I think it should be moved back again. Or if you don't fix the issue for v13 then close it as a won't fix.
