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.
