SingleFieldList : Cannot read property 'map' of undefined

[AntoineAwaida]

I have a List which contains a column as ArrayField, with SingleFieldList inside.

This morning all was going well, but I pushed on my server my platform for deployment ; however on launch, I noticed that all Lists of resources containing ArrayFields with SingleFieldList inside crashed, with SingleFieldList : Cannot read property 'map' of undefined uncaught error.

What you were expecting:
That the list would be displayed.

I thought it would be the same issue that ids one (#4916), but the PR fix didn't work.

What happened instead:
List doesn't appears, with "A problem has occured" error.

Steps to reproduce:

Go to admin.hublo.eu with these credentials
See that abonnements page crashes (db is still empty in other resources, but on local version it works)

Related code:

export const AbonnementList = (props) => (
  <List {...props} filters={<FullFilter />}>
    <Datagrid rowClick='edit'>
      <TextField source='id' />
      <TextField source='name' />
      <TextField source='price' />
      <TextField label='Période de facturation' source='pricePeriod' />
      <TextField label="Période d'octroi des crédits" source='offeredPeriod' />

      <ArrayField source='descriptions'>
        <SingleFieldList linkType={false}>
          <TextField source='description'></TextField>
        </SingleFieldList>
      </ArrayField>
      <EditButton />
    </Datagrid>
  </List>
);

Sorry, wasn't able to reproduce it with your sandbox.

Just replaced SingleFieldList with Datagrid and it worked fine.
I'll try to investigate if I have time.
