How can I add `json` type field input on Admin User?

System Information
  • Strapi Version: 3.3.4

  • Database: mongo

I added settings field on model & validation logic.
Editing through api works well.

But I wanted to show this field on Admin Panel so I modified two files below.

On strapi-admin/admin/src/containers/Users/EditPage/utils/form.js

  // added
  settings: {
    label: 'Settings',
    type: 'json',

On strapi-admin/admin/src/containers/Users/EditPage/index.js

useUsersForm(`/admin/users/${id}`, editValidation, cbSuccess, [
    // added

But the field shows error text This json is not available.

What should I do next?

I solved it by copying InputJSON and InputJSONWithErrors component from strapi-plugin-content-manager.

And use it on strapi-admin/admin/src/components/IntlInput/index.js like below.

      // register as customInput
        json: InputJSONWithErrors,
