Microsoft bot framework - Returns 502 error from task/fetch

I have an MS Teams adapter written using the botframeworks sdk v4 for node js which works perfectly for normal conversations. But when I try to do a task/fetch, it returns an error message "Unable to reach app. Please try again." on the task module popup Unable to reach app. Please try again. 502 error messages unable to invoke

    Added a ** handleTeamsTaskModuleFetch ** server side action inside bot section.
