Hi, I am experiencing same issue as decribed here:
In both cases, question was the same - how do I fix this.
Currently I have run into exactly same issue, and I'd like to fix this. I don't want to upgrade ES/Kibana stack. I just want to get this fixed, so I can start using my old visualisations and dashboards. I don't mind whether the one which caused this doesn't work, I am more interested in getting my service up and running again.
