Cannot render a form for a valid JSON schema

Prerequisites

• I have read the documentation;
• In the case of a bug report, I understand that providing a SSCCE example is tremendously useful to the maintainers.

Description

The form shows an error for a part of valid JSON schema

Steps to Reproduce

Provide the folllowing JSON schema (from https://github.com/Azure/open-service-broker-azure):

{
  "$schema": "http://json-schema.org/draft-04/schema#",
  "properties": {
    "firewallRules": {
      "description": "Firewall rules to apply to instance. If left unspecified, defaults to only Azure IPs",
      "items": {
        "description": "Individual Firewall Rule",
        "properties": {
          "endIPAddress": {
            "description": "End of firewall rule range",
            "type": "string"
          },
          "name": {
            "description": "Name of firewall rule",
            "type": "string"
          },
          "startIPAddress": {
            "description": "Start of firewall rule range",
            "type": "string"
          }
        },
        "required": [
          "name",
          "startIPAddress",
          "endIPAddress"
        ],
        "type": "object"
      },
      "type": "array"
    },
    "location": {
      "description": "The Azure region in which to provision applicable resources.",
      "type": "string"
    },
    "resourceGroup": {
      "description": "The (new or existing) resource group with which to associate new resources.",
      "type": "string"
    },
    "sslEnforcement": {
      "default": "",
      "description": "Specifies whether the server requires the use of TLS when connecting. Left unspecified, SSL will be enforced",
      "enum": [
        "",
        "enabled",
        "disabled"
      ],
      "type": "string"
    },
    "tags": {
      "additionalProperties": {
        "type": "string"
      },
      "description": "Tags to be applied to new resources, specified as key/value pairs.",
      "type": "object"
    }
  },
  "type": "object"
}

Expected behavior

Rendering the whole form

Actual behavior

Rendering the form until the tags key appears

Invalid tags object field configuration:Cannot convert undefined or null to object.

{"additionalProperties":{"type":"string"},"description":"Tags to be applied to new resources, specified as key/value pairs.","type":"object"}

This part is problematic:

"tags": {
  "additionalProperties": {
    "type": "string"
  },
  "description": "Tags to be applied to new resources, specified as key/value pairs.",
  "type": "object"
}

Commenting it makes the error disappear.

If you make a pull request I will review it and merge it if ok. rjsf is in fact not actively maintained.
