Error 'Unexpected response from server' when opening a workspace in Workspace Browser

[fisuda]

I encountered the 'Unexpected response from server' error when opening a workspace in the Workspace Browser. This is because the workspace has an empty name. The name of the workspace structure will be empty when renaming a workspace name to a name that consists only of multibyte characters.

GET /api/workspace/32

{
  "id": "32",
  "name": "",
  "title": "\uff37\uff49\uff52\uff45\uff23\uff4c\uff4f\uff55\uff44",
  "public": false,
  "shared": false,
  "requireauth": false,
  "owner": "admin",
  "removable": true,
  "lastmodified": 1624743022724,
  "description": "",
  "longdescription": "",

   ...ETC...

}

• How to reproduce
