{% include %} tags do not accept arbitrary expressions

[wardourdigital]

Environment
Node version: v14.16.0
simple-nunjucks-loader version: 3.1.0
webpack version: 5.37.1

Webpack

{
    test: /\.njk|html$/,
    use: [{
        loader: "simple-nunjucks-loader",
        options: {
            searchPaths: ["src-local-nunjucks/templates", "src-hubspot-theme/modules"],
            filters: {
                filter: path.join(__dirname, "filter.js"),
            },
        },
    }, ],
},

Describe the bug
According to the documentation of nunjucks:

include actually accepts any arbitrary expression, so you can pass anything into it, as long as the expression evaluates to a string or a compiled Template object: {% include name + ".html" %}.
Include

When I attempted to do this:

{% macro getBlock(name) %}
    {% include name + '-module/module.html' %}
{% endmacro %}

{{ getBlock("card-section") }}

I get the error:

ERROR in Error: Child compilation failed:
  Module build failed (from ./node_modules/simple-nunjucks-loader/lib/cjs/loader  .js):
  TypeError: Cannot read property 'split' of undefined

Expected behavior
For the named template to be included into the page.

Thank you for your report, will look at this issue on the weekend.

I have add warnings for such imports. Full support is on the way.

[jakefentress]

This would be a huge help to have supported. Any news or tips for workarounds?

[ogonkov]

I have started to refactor imports/assets in #121 to use same flow for both to load dynamic assets (imports with variables), but it's still WIP.

[jakefentress]

A little bump here. Is this still under development?

[ogonkov]

Yes, it still priority. Loader code is a bit of mess. I planned to convert it to TS first, to have more control over all the abstractions.

@wardourdigital @jacobfentress

Did anyone figure out a solution for this?

I'm also having the same issue when including a named template inside a Macro.

ModuleBuildError: Module build failed (from ./node_modules/simple-nunjucks-loader/lib/cjs/loader.js):
TypeError: Cannot read property 'split' of undefined

Hello, still on it. Sorry for delay.
