Getting Invalid Response from API . - Groovy Scripting - rest

Question

I am trying a POST method in groovy which basically creates a Issue in Jira . I am getting invalid response from the API . However in postman I could able to get the response . I have searched few questions in stackoverflow where they are recommending to set the Accept-Encoding to "" . I tried out different methods but it didnt work .
Code :

Solution from #dagget :
// use the below code when reading it from input stream
accept-encoding : identity
responseStream = new java.util.zip.GZIPInputStream(responseStream)
