Hi @zaeemmasood

Sorry you have not provided not enough information for us to help

What Version are you on?

What has changed (something) the index template, index name something, the index rolled over with no template.

Something changed...

Please provide the mappings for that index

Open one of those documents

Get the Index Name

Go To Kibana -> Dev Tools

Run

GET your-index-name

And share the results
