Implementation restrictions

• The PDF reports capability must not use any AngularJS related feature.

Tasks

• Adapt the existing PDF report feature to use embeddable dashboards
• Adapt the generation of PDF reports

Problem

After updating the development branch and trying to generate the PDF report on Theat Hunting application that has already replaced the dashboard, I got errors. It seems the old dashboard is rendered and causes that take screenshots of visualizations that are not rendered, and this causes a problem when building the PDF report on the backend side.

This issue #6594 should remove the render of the old dashboard, and this problem should disappear.

Problem

I found a problem on the generation of PDF report of Amazon Web Services related to the geolocation map visualization. It seems the library to convert the DOM node to image fails. I reviewed the previous versions and this visualization is not included on the reports, so this should be a known issue: #5086.

I will try to research if we can solve this.

Update 2024/05/02

I continue researching about the problem related to converting to png the map visualization on the Amazon Web Services application.

I found an issue abut the error: tsayen/dom-to-image#455

Update:
I found a possible solution applying a patch to the dom-to-image library:
tsayen/dom-to-image#243 (comment)
