elk:740 - PDF-Export of Dashboards does not work

[rflume]

Hi,

I am using the Docker image sepb/elk:740.

Just wanted to try out the PDF-Export feature to export my Dashboard so I activated the trial license. However, the export fails with the error message:

Unable to generate report
Error: Error spawning Chromium browser: [Error: Protocol error (Target.setDiscoverTargets): Target closed.]

The error logs are:

Any idea how to solve it? Or is the export even possible on trial?

Thanks in advance for looking into it!

I'm afraid I'm going to close this issue, as it is a question on the use of the ELK services that is not specific to this Docker image. I would recommend seeking guidance from the ELK forums over at https://discuss.elastic.co/.
