Swagger Codegen No Property for null

I'm trying to compile server code using swagger-codegen, however I'm hitting an error with my file that won't generate.

I'm running on Ubuntu.

export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64

git clone https://github.com/swagger-api/swagger-codegen.git

Swagger generate command is copied largely from the ./bin 

#!/bin/sh

SCRIPT="$0"

while [ -h "$SCRIPT" ] ; do
  ls=`ls -ld "$SCRIPT"`
  link=`expr "$ls" : '.*-> \(.*\)$'`
  if expr "$link" : '/.*' > /dev/null; then
      SCRIPT="$link"
  else
SCRIPT=`dirname "$SCRIPT"`/"$link"
fi
done

if [ ! -d "${APP_DIR}" ]; then
  APP_DIR=`dirname "$SCRIPT"`/..
  APP_DIR=`cd "${APP_DIR}"; pwd`
fi

executable="./modules/swagger-codegen-cli/target/swagger-codegen-cli.jar"

if [ ! -f "$executable" ]
then
  mvn clean package
fi

# if you've executed sbt assembly previously it will use that instead.
export JAVA_OPTS="${JAVA_OPTS} -XX:MaxPermSize=256M -Xmx1024M -DloggerPath=conf/log4j.properties"
ags="$@ generate -i modules/swagger-codegen/src/test/resources/2_0/trustmile-consumer-small.json -l nodejs -o samples/server/trustmile/nodejs"

java $JAVA_OPTS -Dservice -jar $executable $ags

Here's the error in condensed form:

ERROR io.swagger.models.properties.PropertyBuilder - no property for null, null
java.lang.NullPointerException
at io.swagger.codegen.DefaultCodegen.fromParameter(DefaultCodegen.java:995)
at io.swagger.codegen.DefaultCodegen.fromOperation(DefaultCodegen.java:816)

at io.swagger.codegen.cmd.Generate.run(Generate.java:124)
at io.swagger.codegen.SwaggerCodegen.main(SwaggerCodegen.java:35)

And the spec here: https://gist.githubusercontent.com/jorourke/79897a93e15bf4d20eab/raw/87e520e1d79d721b5471a5009546b58f2131e891/Swagger%2520API%2520Spec

I am somewhat at a loss as the swagger spec works in Swagger Editor

Any help greatly appreciated.

swagger-codegen does not support inline schema at the moment. The issue is track here.

To workaround the issue, you can define the parameter schema with a proper model in "definitions" section instead.

UPDATE (2016/06/28): Swagger Codegen now supports inline schema. Please pull the latest master to generate API clients, server stubs or documentation (https://github.com/swagger-api/swagger-codegen#getting-started)
