Question

Traceback (most recent call last):
  File "/opt/odoo/sources/odoo/odoo/tools/cache.py", line 85, in lookup
    r = d[key]
  File "/opt/odoo/sources/odoo/odoo/tools/func.py", line 71, in wrapper
    return func(self, *args, **kwargs)
  File "/opt/odoo/sources/odoo/odoo/tools/lru.py", line 34, in __getitem__
    a = self.d[obj]

In odoo 15, you can't inherit web.assets_backend in view and can't add your js or css. You need to add it in manifest file. I share example code.
Add this code to manifest file.

'assets': {
        'web.assets_backend': [
            'pos_address/static/src/js/yourjs.js',
        ],
    },
