"Auto-fix" of Swym snippet crashes the server and literally deletes the file.

[ConduciveMammal]

Describe the bug So, in the process of installing Swym wishlist onto a theme, when I create a new file called swym-product-view.liquid and then auto-fix any issues, theme-check server will first crash and then somehow delete the entire file.

Here is the code from the snippet:

{% if product %}
  <script class="swym-product-view-snippet">
  ['SwymViewProducts', 'SwymWatchProducts', 'SwymProductVariants'].forEach(function(k){
    if(!window[k]) window[k] = {};
  });
  (function(et){
      var collections = {{product.type | json}};
      var o={}, empi={{ product.id | json }},
      piu = {{ product.featured_image | json }};
      {% assign currentVariant = product.variants[0] %}
      {% for variant in product.variants %}
      {% if variant.selected %}
      {% assign currentVariant = variant %}
      {% endif %}
      SwymProductVariants[{{variant.id|json}}] = {
        empi:empi,epi:{{variant.id|json}},
        du:"{{ shop.url }}{{ product.url }}",
        dt:{{ product.title | json }},
        iu: {{ variant.image.src | json}} || piu,
        stk: {{variant.inventory_quantity}},
        pr: {{ variant.price }}/100,
        {% if variant.compare_at_price %} op: {{variant.compare_at_price}}/100, {% endif %}
        variants: [{ {{ variant.title | json }} : {{variant.id|json}}}]
      };
      SwymWatchProducts[{{variant.id | json}}] = o[{{variant.id | json}}] = {"id": {{variant.id | json}}, "available": {{variant.available | json}},"inventory_management": {{variant.inventory_management | json}},"inventory_quantity": {{variant.inventory_quantity | json}},"title": {{variant.title | json}}, "inventory_policy": {{variant.inventory_policy | json}}};
      {% endfor %}
      var product_data = {
        empi:empi, epi:{{ currentVariant.id }},
        dt  :{{ product.title | json }},du:"{{ shop.url }}{{ product.url }}",
        ct  :collections,pr:{{ currentVariant.price }}/100,stk:{{ currentVariant.inventory_quantity }},
        iu  :{{ currentVariant.image.src | json }} || piu,variants:[{ {{currentVariant.title | json}} : {{currentVariant.id | json}} }]
        {% if currentVariant.compare_at_price %} ,op:{{currentVariant.compare_at_price}}/100 {% endif %}
      };
      SwymViewProducts[{{product.handle | json}}] = SwymViewProducts[{{product.id | json}}] = product_data;
      SwymWatchProducts[{{product.handle | json}}] = SwymWatchProducts[{{product.id | json}}] = o;
    })();

  </script>
  {% endif %}

Steps to reproduce

• Create a new theme snippet and save it as swym-product-view.liquid (I'm unsure if the name matters).
• Paste the above code into the file and save
• theme-check will produce a bunch of warnings
• Open the Quick Fix panel and select Fix all auto-fixable problems
• theme-check should now crash and then the file is deleted somehow.

👋🏻 Hi @ConduciveMammal! Thanks for reporting this. Unfortunately the Ruby version of theme check has been deprecated for some time. Would you be able to confirm you are still having issues when using our maintained version of theme check? This is done using either the latest version of the Shopify CLI, or via the Shopify Liquid Visual Studio Code extension.

If you are still having issues, please raise an issue over in the CLI or theme tools repositories. Thanks!
