CreateModel gives "Card template ... has a problem.<br>See the preview for more information."

I have a PowerShell script that reads templates and imports them into Anki. I'm currently having an issue with importing one of them and the error given isn't very descriptive.

I've taken a look at the Card template has a problem page in the Anki docs but all of those have descriptions.

This is the json I'm sending to Anki-Connect

{
  "params": {
    "cardTemplates": [
      {
        "Name": "st listen",
        "Front": "<!-- Fields:Source ID,ChapterSection,Occurance,st,tst,Chapter,Section,sid -->\n<link href=\"./norwegian_template.css\" rel=\"stylesheet\" />\n\n<table class=\"front-card\">\n    <thead>\n        <tr>\n            <th>Skriv hva de sier . . .</th>\n        </tr>\n    </thead>\n    <tbody>\n        <tr>\n            <td>{type:st}</td>\n        </tr>\n        <tr>\n            <td>{sid}</td>\n        </tr>\n    </tbody>\n    <tfoot>\n        <tr>\n            <td>Kapittel {chapter}</td>\n        </tr>\n        <tr>\n            <td>Del {section}</td>\n        </tr>\n    </tfoot>\n</table>\n\n<script src=\"./norwegian_template.js\"></script>",

    ],
    "modelName": "NN-SET Type 1",
    "inOrderFields": [
      "Source ID",

      "Section",
      "sid"
    ],

  },

}

This is the error I get back

{
  "result": null,
  "error": "Card template ⁨1⁩ in notetype '⁨NN-SET Type 1⁩' has a problem.<br>See the preview for more information."
}

I'm not sure if this is an issue in the HTML templates or a something with Ank-Connect communicating with Anki? We can manually add this template and Anki accepts it without issue.

This is the HTML that is parsed out and added to the front/back of the card template being sent.

<table class="front-card">
    <thead>
        <tr>
            <th>Skriv hva de sier . . .</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>{{type:st}}</td>
        </tr>
        <tr>
            <td>{{sid}}</td>
        </tr>

    <tfoot>

        <tr>
