Using datasource cloudstack_template crashes the provider

[codemoos]

Plugin crashes when passing name = display_text in datasource cloudstack_template, as shown below code block.

data "cloudstack_template" "my_template" {
  template_filter = "featured"

  filter {
    name = "display_text"
    value = "Ubuntu 22.04"
  }
}

What does work is passing name = name with value = "Ubuntu"

data "cloudstack_template" "my_template" {
  template_filter = "featured"

  filter {
    name = "name"
    value = "Ubuntu 22.04"
  }
}

Error: The terraform-provider-cloudstack_v0.4.0 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

Seems like a duplicate of #42. I also provided a fix for this issue which is merged already #43. Are you on the latest build @codemoos ?

[codemoos]

Aah thanks, did not see that one. But the latest release is from feb 2022, this fix is merged after.

[Damans227]

I see. Can you do a quick test, and use following as a filter:

  filter {
    name = "displaytext"
    value = "Ubuntu 22.04"
  }
}

If that works, then you can use it as a workaround for now. The fix shall become available in the next release.

[codemoos]

Yes, that works!
