*Field not rendering in Create, only in Edit

[gartner]

What you were expecting:
I'm using an ArrayInput, with a SimpleFormIterator, which again has a FormDataConsumer, to let me include a FunctionField or TextField in a form.

What happened instead:
When this is used inside an Edit, it does render all the fields, both FunctionField and TextField. But when in a Create, only Inputs are displayed - not Fields.

Steps to reproduce:
Codesandbox

I have added a Codesandbox which demonstrates the problem: When editing the record with posts, the TextField is displayed. But when creating a new record, it is not, only Inputs are shown.

Th edit view works fine in your example, is the create that has a problem

You can get it like this:

<Labeled label="Body">
    <FunctionField
        /* @ts-ignore */
        render={record => {
            return record.body;
        }}
        /* @ts-ignore */
        source={getSource('body')}
        record={scopedFormData}
    />
</Labeled>
