HI,
I think there is two bug in Settings page and setting data stored unexpected format in PluginStore. Due this bugs settings page and store not working.
In admin/src/pages/Settings/index.js line 27 res.data.settings is wrong I need to correct it to res.data because there is no settings key.
In admin/src/api/task.js line 15 body key isn’t valid due the code never use it. Correct code is
setSettings: async data => {
return await axiosInstance.post(`/todo/settings`, data);
},
