We wrote a script that generates and download PDF reports from Kibana visualisations. This script has always been working fantastic. Since we have upgraded to 7.7 and later to 7.8 we get PNG's like this:
Some times the PNG's are as expected and sometimes they don't. We have set a timeout of 90 seconds on the rest client that downloads the png's.
We also first check if the PNG is ready before downloading it.
I'm I the only one having this problem or is this a known issue?
