welcome to the forum @Mouly_Infy

This has been asked directly or indirectly a couplee of times, e.g. [here](https://discuss.elastic.co/t/context-length-is-bigger-than-maximum-allowed-string/356985)

See this [github](https://github.com/elastic/kibana/issues/173346) thread too for some ideas.

You need be careful here too as other clients (not just Kibana/Discover) can hit issues with large HTTP payloads. I dont know your use case and what you are specifically trying to do, but it's unlikely there is much value in "seeing" a 23 MB document within Kibana.
