[Dashboard] Cannot complete generating a PDF or PNG report

[TinaHeiligers]

Kibana & Elasticsearch version:
7.16

Browser:
Safari Version 15.0 (16612.1.29.41.4, 16612)

Environment
Cloud (admin staging)

Describe the bug:
In Dashboards, there's an option to create a report that should complete and be downloadable from the Reporting app. This should also be the case now with the ability to generate reports from Dashboards that have unsaved changes.

When using Safari, the reporting job for PNG and PDF reports errors out when the a PNG or PDF report is generated from a Dashboard with unsaved changes.

Steps to reproduce:

1. With Safari, Navigate to the Dashboard app
2. Select an existing Dashboard or create a new one
3. Edit the dashboard (if using an existing one) or add a visualization if creating a new Dashboard.
4. Do not saved the changes/addition
5. Generate a report (either PDF or PNG)
6. Wait for a few minutes for the report to generate
7. Navigate to the Reporting application
8. Observe that the PNG/PDF report has errors.

Expected behavior:
The report should generate successfully.

Screenshots (if relevant):

Errors in browser console (if relevant):

Provide logs and/or server output (if relevant):
No warnings or errors observed.

This appear to be a duplicate of: #106873 - The report not generating is possibly due to it being a large dashboard, can you confirm? Do all reports for a smaller dashboard also fail on Mac OSX or just this one?

Diagnostic fails is also known here: #106873 (comment) but has been fixed recently here: #116199

The dashboard isn't all that big but does span quite a lot of data. I confirmed the bug using a much smaller dataset powering the dashboards and a small dashboard from Kibana sample data too ("By Value DB" uses the Kibana logs sample data set).

@TinaHeiligers does your cloud instance have 4GB of Memory? Reporting on cloud recommends around that much and it isn't the default https://www.elastic.co/guide/en/kibana/current/reporting-troubleshooting.html#reporting-troubleshooting-system-requirements

[TinaHeiligers]

@poffdeluxe If 4GB isn't the default then I doubt the instance had that much allocated to it. Unfortunately, that specific deployment was auto-terminated so I can't check that one specifically.

[liza-mae]

The default on cloud is 1GB

[TinaHeiligers]

The default on cloud is 1GB

I upgraded a different 7.16 deployment's Kibana to 4GB and generating the PNG report from an unsaved dashboard created from visualizations added by value works as expected.

Closing this issue as it isn't a bug.
