this morning i have done an update from 6.2.4 to 6.4.3 and have now a problem with a bar chart visualization in Kibana.
Each time i try to load it Kibana gives the message "Cannot read property 'map' of undefined".
I have centered the problem around the "Group other values" function.
Here is the configuration of the visu (the metric is only a count):
If i remove one of the "Group other values" the visu is working.
Can someone help me how i can get it working again?
If you need sample data, ask and i will post some.
Thanks for your help
