Online point of sale items not showing

ERPNext

I have made pos profile for online pos. But when i open pos items are not showing. I have tried both check and uncheck of “Display Items In Stock” but still it’s not showing. I have stock balance in that specific warehouse.
There is no error in js console
Current configuration

ERPNext: v11.0.3-beta.24 () (develop)
Frappe Framework: v11.0.3-beta.29 () (develop)

python version 2.17rc

If Display Items In Stock is unchecked in pos profile then i face an error

I think by moving to V11 master would help. There are no further developments on develop (beta). Not sure but might just work.
