Clojurians Log v2

I have used future for multhreading in core-async. Here is the screenshot of my code and error message. I got null pointer exception for using future. If i use just

(async/thread-call (process-data-chan))

(future (async/thread-call (process-data-chan)))

Neither of those is correct

Calling thread or thread-call like that in a future is making a new thread in a new thread

thread-call takes a function and you are passing it nil

The result of calling your function

thread is the macro like future

Replacing future with thread is pointless unless you are using go blocks which need to park in the result, the both just run whatever on a thread pool, no difference except the return value which doseq throws away
