No idea, sorry. Please don't ping random folks to draw them into a conversation. We're all volunteers here and it's really rather rude to demand attention like that. ---

If someone is going to be able to help I would recommend you provide more details about exactly the steps you have taken and what the environment look like. Also provide more of the logs so there is some context. ---

I have the same issue after upgrading my environment from 7.17 to 8.11. Sorry about bringing up an old topic. Googling my error only returned this page as a result. My assumption from reading the documentation is that a new config value was added for licensing as I now see there is talk about free and subscription features. However, I was unable to find any reference to config values or how to update the config file with any of the upgrade documentation located. Any help would be appreciated. ---

Hello and welcome, Are you doing this same update path from 7.17.8 to 8.12.2? I would suggest that you open a new topic with your specific issue and share the logs you have with the error. ---

it got resolved by restarting the elasticsearch and kibana service again
