Research direction

Start with the linked adminTest reproduction and trace how the Admin renders API relationships when readableLink is true or false. Reproduce the collection and single-object cases, then verify that subobjects display correctly and that the Admin no longer crashes with data.map or invalid element errors.

Written by the indexing model from the issue text.

Description

API Platform version(s) affected: 3.2.16

Description
With readableLink false Collection displayed as links, single is empty:

    #[Groups(groups: ['Main:write'])]
    #[ORM\OneToMany(mappedBy: 'main', targetEntity: Sub::class, orphanRemoval: true, cascade: ['remove', 'persist', 'refresh', 'merge', 'detach'])]
    #[ApiProperty(readableLink: false, writableLink: false)]
    private Collection $subs;

    #[Groups(groups: ['Main:write'])]
    #[ApiProperty(readableLink: false, writableLink: false)]
    #[ORM\ManyToOne(inversedBy: 'mains', cascade: ['remove', 'persist', 'refresh', 'merge', 'detach'])]
    private ?One $one = null;

With readableLink true Collection displayed as json:

    #[Groups(groups: ['Main:write'])]
    #[ORM\OneToMany(mappedBy: 'main', targetEntity: Sub::class, orphanRemoval: true, cascade: ['remove', 'persist', 'refresh', 'merge', 'detach'])]
    #[ApiProperty(readableLink: true, writableLink: true)]
    private Collection $subs;

With readableLink true Object, Admin crashes:

    #[Groups(groups: ['Main:write'])]
    #[ApiProperty(readableLink: true, writableLink: true)]
    #[ORM\ManyToOne(inversedBy: 'mains', cascade: ['remove', 'persist', 'refresh', 'merge', 'detach'])]
    private ?One $one = null;
