Hi there,
I’m currently working on an integration involving ERPNext, Frappe CRM, and Lending. In older versions of Frappe, we were able to switch between apps directly from the sidebar. However, in the newer versions, this behavior seems to have changed — instead of app switching, the desk now shows icons based on modules (as I understand it).
Since the CRM portal uses a separate Vue-based frontend, it still displays the older-style app switcher and allows switching between apps (as shown in Image 1).
The issue arises when I select the Lending app from this list — I get redirected to the Lending app, but it immediately throws an error (as shown in Image 2).
I’d appreciate some insight into whether this is:
an expected behavior due to changes in how app/module navigation works in newer Frappe versions,
a configuration issue on my side, or
a known bug on the Frappe/Lending side.
Any guidance on how to properly handle app switching in this setup, or how to resolve this error, would be greatly appreciated.
