Stream pages in Notion source has incorrect schema for field properties

[grishick]

Stream pages has a field properties which is an array of objects. The objects are defined as oneOf and describes several types of objects that can appear inside properties array. One of these object variations can have 3 fields: id, type, and title defined as following:

{
									"type": "object",
									"properties": {
										"id": {
											"type": "string"
										},
										"type": {
											"enum": ["title"]
										},
										"title": {
											"properties": {
												"text": {
													"type": ["null", "array"],
													"items": {
														"type": ["null", "object"],
														"properties": {
															"href": {
																"type": ["null", "string"]
															},
															"text": {
																"type": ["null", "object"],
																"properties": {
																	"link": {
																		"type": ["null", "object"],
																		"properties": {
																			"url": {
																				"type": ["null", "string"]
																			},
																			"type": {
																				"enum": ["url"]
																			}
																		},
																		"additionalProperties": true
																	},
																	"content": {
																		"type": ["null", "string"]
																	}
																}
															},
															"type": {
																"type": ["null", "string"]
															},
															"plain_text": {
																"type": ["null", "string"]
															},
															"annotations": {
																"type": ["null", "object"],
																"properties": {
																	"bold": {
																		"type": ["null", "boolean"]
																	},
																	"code": {
																		"type": ["null", "boolean"]
																	},
																	"color": {
																		"type": ["null", "string"]
																	},
																	"italic": {
																		"type": ["null", "boolean"]
																	},
																	"underline": {
																		"type": ["null", "boolean"]
																	},
																	"strikethrough": {
																		"type": ["null", "boolean"]
																	}
																},
																"additionalProperties": true
															}
														},
														"additionalProperties": true
													}
												},
												"type": {
													"type": ["null", "string"]
												}
											}
										}
									}
								}

the bug in this schema definition is that the actual data looks like this, where title is an array of objects:

"properties": [{
			"name": "title",
			"value": {
				"id": "title",
				"type": "title",
				"title": [{
					"type": "text",
					"text": {
						"content": "blahblah",
						"link": null
					},
					"annotations": {
						"bold": false,
						"italic": false,
						"strikethrough": false,
						"underline": false,
						"code": false,
						"color": "default"
					},
					"plain_text": "blahblah",
					"href": null
				}]
			}
		}],
