I've used Json.parse in multiple places. I think Play doesn't expose a way to configure this limit globally. Will I have to create a custom ObjectMapper everywhere ?

Will take a look at this in the course of upgrading jackson.

@RiteshBM Play does not support Jackson 2.15 or above. Jackson 2.15 introduced StreamReadConstraints and Play has not yet implemented anything to allow users with very large JSON docs to override the default Jackson settings.

Stick with Jackson 2.14.

@pjfanning Does it mean I can't use Play without bypassing this limit if other packages require jackson > 2.14.

Try calling this method to override the StreamReadConstraints.
