Datastore functionality does not work

Excepted Result
Using datastore functionality we should able to share data in scenario, spec and suite level.

Actual Result
Datastore functionality does not work. While fetching key, value is showing as null.
Kindly find the below console output:

@Debashis9012 please share the spec and implementation used to check this. Datastores can fetch only values that are written previously.

This issue happens with gauge-js. When we add a key-value in beforeScenario and try to access it in afterScenario.

In gauge-js the data stores are being cleared even before running the After* hooks.
The issue is at https://github.com/getgauge/gauge-js/blob/master/src/message-processor.js#L119-L122
