You are using a form view which contains a field with the `widget` attribute set to `code` which is not a widget supported by the standard client.
Maybe your code depends on a client plugin that register such widget.

Yes, if you’re using the `html_report` or `babi` modules both depend on the `widgets` module and you must use a patched version of sao to include those widgets.
I can provide that to you but note that it will only work starting on version 6.8 and you need to use sao.
