Why am i not able to pass context variable in run time for a service

Hope you have gone through https://developer.kore.ai/docs/bots/bot-builder-tool/dialog-task/working-with-the-service-node/#Define_a_Custom_Service

Inside the body you can have keys like

{
“key” : {{ context.session.BotUserSession.varName }}
}

i do followed that link and during run tine if i set the body to custom and content-type to application/json and while running it was automatically getting changed from custom to application/json.

Not sure what you exactly mean that it was automatically getting changed from custom to application/json. That could be a UI issue though. Can you be little more more specific?
If you can share a curl (something that works) and let me know which parameter you want to pass in body, I can probably try to help.

FYI - Double-checked the platform behavior. All the below work:

application/json

custom - with double quote (irresteptive of having content-type = application/json in the header)

custom - without double quote (irresteptive of having content-type = application/json in the header)
