I have a similar issue with the PropertyGenerator. When I define a properties type as Array in spotlight.io, the generation fails with
Fatal error: Uncaught TypeError: ApiPlatform\SchemaGenerator\OpenApi\Model\Type\PrimitiveType::__construct(): Argument #1 ($name) must be of type string, array given, called in ../vendor/api-platform/schema-generator/src/OpenApi/PropertyGenerator/PropertyGenerator.php on line 116.

It is caused by a type definition in the schema json like:

 "propertyName": {
    "type": [
      "boolean",
      "null"
    ],
    ...

i've got same problem

Looks like the we have to fix openapi, because (in my case), i want to describe nullable field as.

"releasedAt": {
      "type": [
          "string",
          "null"
      ],
      "format": "date-time"
  },

Openapi docs say this way is incorrect:

I generated openapi with ApiPlatform's bin/console api:openapi:export --spec-version=3, so the root problem is in openapi generation
