I have a customer, which updated to Splunk 7.2.6. and since then, the scheduled PDF delivery of his dashboards is not working anymore. While sendemail works fine, the dashboards are not sent at all.
I can recreate the scenario locally.
The job has run, but said "No items matched", while the dashboard has content.
The dashboard is neither advancedXML nor a form. It contains just two simple searches. The customer has admin rights.
