null pointer exception when transforming pftaps file to a bulk of jsons

I am not able to reproduce the error. Instead the software throws an warning for the record. The code was last edited July 2019, have you updated and rebuilt since then?

I pulled the repo a week ago and use the master branch as the source. and I just retried it with pulling from master and build the .jar anew. could you please affirm my building steps are right?

1. pull repo
2. cd to $REPO_ROOT/BulkDownloader/
3. run mvn package
4. get an error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:3.1.1:single (default) on project BulkDownloader: Error reading assemblies: Error locating assembly descriptor: resources/assembly/bin.xml

5. copy $REPO_ROOT/resources/assembly/bin.xml to $REPO_ROOT/BulkDownloader/ to avoid that error
6. run mvn package again with success result
7. cd BulkDownloader/target/dependency-jars
8. unzip all jars and create a new dependency.jar file containing all dependency folders:

mkdir dependencies
unzip \*.jar -d dependencies/
cd dependencies
jar cf dependency.jar *

9. cd BulkDownloader/target/classes
10. create a manifest file with the following content:

Manifest-Version: 1.0
Created-By: 1.7.0_06 (Oracle Corporation)
Main-Class: gov.uspto.bulkdata.cli.Transformer
Class-Path: dependency.jar

11. run jar cfm transformer.jar manifest.txt gov/*
12. put together transformer.jar and dependency.jar and use the transformer.jar as following:
    java -jar transformer.jar -f=pftaps19760203_wk05.zip --type=json --outDir=. --outBulk=false --prettyPrint=true

After pulling the repo run "maven clean package" from the top level directory (not from within BulkDownloader). If test are failing, you can skip test with "maven clean package -DskipTests=true".
If the maven build is successful a zip file should be created under target; "./target/PatentPublicData-0.0.1-SNAPSHOT-*.zip".

If the maven build is successful a zip file should be created under target; "./target/PatentPublicData-0.0.1-SNAPSHOT-*.zip".

The build was successful, the snapshot file has been created. But the same .jar creation algorithm leads to the same null pointer exception.
And the same exception at the same file point also happens if I avoid all custom algorithms and run the tool as it is, with no hand made .jar files:

cd PatentPublicData/BulkDownloader

java -cp "target/BulkDownloader-0.0.1-SNAPSHOT.jar:target/dependency-jars/*" gov.uspto.bulkdata.cli.Transformer -f="pftaps19760203_wk05.zip" --type="json" --outDir="." --matching-xml=true --outBulk=false
