java.io.EOFException when parsing JSON with clojure Transit

Question

I am reading from an input stream with (t/read request-body :json) and I get a java.lang.RuntimeException: java.io.EOFException.

{"A":"B", "C":"D"}
java.lang.RuntimeException: java.io.EOFException
                   ReaderFactory.java:122 com.cognitect.transit.impl.ReaderFactory$ReaderImpl.read
                  TransitFactory.java:136 com.cognitect.transit.TransitFactory$DeferredJsonReader.read
                          transit.clj:285 cognitect.transit/read

Any ideas why this could be?

For clarity the curl POST request:

%curl -X POST ...../word -H "Content-Type: application/json" -d '{"A":"B", "C":"D"}' -v > abc.html 
* Hostname was NOT found in DNS cache
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

Looking at your logging data, your request body is not actually json, it looks like a multi-part/form-data encoded form which includes a json file-upload.

thanks, I changed the post request's type using curl and updated the question accordingly

OK that looks better. Note that you can read a request body only once. If your code prints the body for debugging and then tries to read it again for parsing that will give an EOF error.
