Facing this issue in release version of android app. Working fine in debug app.

I have the same problem, and only in production as well. However, it works correctly in debug. I've tried modifying the proguard file, but I haven't had any luck.

Any solution? @gollobo @SipNWork

Update for you guys:

I solved it after adding the following in proguard rules:

-keepnames class com.fasterxml.jackson.** { *; }
-keepnames interface com.fasterxml.jackson.** {  *; }

Hope it works for you guys too. I finally found this solution almost 3 hours of debugging..
