Unable to load blueprint with null tag

[Deleted user]

For some reason, it seems some blueprints have a null tag.

Example: Brian's Trains - https://www.factorio.school/view/-LaIPNgh8f16V8EwXXpW

When I try and load this page, it fails to display.

Checking the console, shows the stack trace.

TypeError: Cannot read property 'category' of null
    at SingleBlueprint.js:351

Checking the API response for this blueprint shows the following tags - https://www.factorio.school/api/blueprint/-LaIPNgh8f16V8EwXXpW

  "tags": [
    {
      "tag": {
        "category": "mods",
        "name": "ltn"
      }
    },
    {
      "tag": {
        "category": "train",
        "name": "junction"
      }
    },
    {
      "tag": {
        "category": "train",
        "name": "loading station"
      }
    },
    {
      "tag": {
        "category": "train",
        "name": "stacker"
      }
    },
    {
      "tag": {
        "category": "train",
        "name": "track"
      }
    },
    {
      "tag": {
        "category": "train",
        "name": "unloading station"
      }
    },
    {
      "tag": {
        "category": "version",
        "name": "0,17"
      }
    },
    {
      "tag": null
    }
  ]

I believe it is that final null tag that is causing this issue.
