If selecting a Specific Release Number from the generated drop down of the Select Application function there is a error thrown:

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected STRING but was BEGIN_OBJECT

The Release Number is in the form of 1.0.0.

All the drop downs are showing the proper content so the connection to BuildMaster is fine.

Note that the step still works despite the error.
