[nop33]

What happened?

Specified dashboards could not be installed

Did you expect to see some different?

The dashboards to have been installed

How to reproduce it (as minimally and precisely as possible):

Just define the following variable:

grafana_dashboards:
  - dashboard_id: 3662
    revision_id: 2
    datasource: prometheus

Link to the dashboard: https://grafana.com/grafana/dashboards/3662

Environment

Anything else we need to know?:

The dashboard URL works, I can fetch it:

curl --fail --compressed https://grafana.com/api/dashboards/3662/revisions/2/download

[nop33]

When I replace curl with get_url, it works. However, I see that in #77 it was changed from get_url to curl because:

[some] dashboards are so big that they don't fit into some cache used by get_url module

get_url:
  url: "https://grafana.com/api/dashboards/{{ item.dashboard_id }}/revisions/{{ item.revision_id }}/download"
  dest: "{{ _tmp_dashboards.path }}/{{ item.dashboard_id }}.json"

[nop33]

I tested all dashboards that were said to have an issue when using get_url (6239, 704 and 5566) and I am happy to report that it worked for all of them:

So, I will consider switching back to get_url is a valid solution and switch back to it. I'll create a PR.

I just tried but I cannot reproduce your issue

I've had this problem on my own debian 10 hosts for months now, thanks for linking to the PR that fixes it.
