Embedding chart without filter: 404 not found

[hendralinux]

I created a dashboard without the need for any filter, however it seems like the url to be used as src in iframe requires a filter as in ../chart-name/embed?filter_name=value coz simply using ../chart-name/embed or even ./chart-name/embed?dummy returns 404 error.

From sample metadata:

<iframe
  src="/-/dashboards/my-dashboard/my-chart/embed?start_date=2023-01-01&end_date=2023-12-31"
  frameborder="0"
  width="100%"
  height="600"
  allowtransparency
>
</iframe>

@hendralinux: sorry but I cannot reproduce your issue. Could you provide a minimal reproducible sample (metadata.yml, html template) for the issue you are experiencing?

FYI, I tried to reproduce the issue with a minimal example:

• For instance here is a basic dashboard without any filters containing a single chart:

  datasette-dashboards:
    test-dashboard:
      title: Test Dashboard
      description: Some description
      charts:
        test-chart:
          title: Total number of offers
          db: jobs
          query: >-
            SELECT count(*) as count
            FROM offers_view
          library: metric
          display:
            field: count
            prefix:
            suffix: " offers"

• And then in a HTML template, an iframe to embedded the chart:

  <iframe
    src="/-/dashboards/test-dashboard/test-chart/embed"
    frameborder="0"
    width="100%"
    height="600"
    allowtransparency
  >
  </iframe>

• This is working well on my end, without any 404 errors.
