Title:
  [SRU] Cannot list shares in dashboard GUI: "Error: Unable to retrieve
  share list. 'NoneType' object has no attribute 'pop'"

Status in OpenStack Manila Dashboard Charm:
  Invalid
Status in Ubuntu Cloud Archive:
  Fix Released
Status in Ubuntu Cloud Archive yoga series:
  Fix Committed
Status in manila-ui package in Ubuntu:
  Fix Released
Status in manila-ui source package in Jammy:

Bug description:
  [Impact]
  It is impossible to list shares in OpenStack dashboard GUI. Share list is empty and the error message in GUI says: "Error: Unable to retrieve share list. 'NoneType' object has no attribute 'pop'".

  It is however possible to list shares with CLI `manila list` command.

  Versions:
  OpenStack Yoga
  Ubuntu 20.04 Focal
  manila charm: channel yoga/stable, revision 98
  manila-dashboard charm: channel yoga/stable, revision 11
  openstack-dashboard charm: channel yoga/stable, revision 566

  I'm attaching juju overlay bundle with manila-related charms which has
  been used to deploy the environment (overlay-manila.yaml).

  Log files from manila unit for the successful `manila list` call:
  - cli-success_manila-access.log
  - cli-success_manila-error.log

  Output of successful `manila list`:
  - manila-list.out

  Log files from manila and openstack-dashboard units, for failure scenario, when visiting /project/shares/ URL:
  - gui-error_manila-access.log
  - gui-error_manila-error.log
  - gui-error_openstack-dashboard_access.log
  - gui-error_openstack-dashboard_error.log

  [Test Case]
  Deploy openstack with juju, including manila and manila dashboard. Create a share and attempt to list shares via the manila dashboard. This should be successful.

  [Regression Potential]
  I don't see any potential regression. The manila dashboard can't list shares so this will fix that regression. The fix is limited to the share_list() function.

  [Discussion]
  I've confirmed that this is already fixed in the kinetic/zed package.
