Problem: Error: Cannot read property 'length' of undefined
Additional Info:

1. Occurs when editing 'SELECT' permission.
2. Is intermittent and usually occurs on 1 of my 2 roles for a table.
3. Bulk sql/ loadSchema data from server is missing 'permissions.select.computed_fields' empty array
4. I don't have any computed_columns

v1.1.0-beta.2

line 89 - console/src/components/Services/Data/PermissionsSummary/utils.js
permission['computed_fields'] is undefined

 Object.keys(tableFields).forEach(fieldType => {
      noFields = noFields && !permission[fieldType].length;

      allFields =
        allFields &&
        (permission[fieldType] === '*' || 
          permission[fieldType].length === tableFields[fieldType].length);   <-- there is not a computed_fields property on permission
    });

Thanks,
John
