Please run the following commands and share the results. Chances are that somehow the default mappings that we apply on the index creation were not applied to your events scalar index.

• First run the following command

curl -XGET "localhost:9200/_cat/indices/events-training_stats_scalar-*"

2. And then for each of the returned indices run the following:

curl -XGET "localhost:9200/<index_name>/_mappings"
