egmentation error when trying to run pipelineruns from Chapter 10

Hi everyone,

I'm working on Exercise 10, and I'm having trouble running some of the provided pipelineruns in the examples.
Specifically, I'm see a segmentation error in the logs of the pipelineruns after they finish.

administrator@gitops-server:~/Documents/tekton-ci/base$ tkn pr logs -f result-ci
panic: runtime error: invalid memory address or nil pointer dereference

Name:          instavote-ci
Namespace:     default
Description:   This is a pipeline template which performs the follwing tasks:
- Clones a subset of file for one microservice from a mono-repo
  e.g. vote/* result/* worker/* matching patterns provided.
- Lists all the files from the cloned workspace to validate if 
  it has cloned the correct subpath matching your microservice. 
- Builds a container image from the workspace which contains 
  the Dockerfile. It accepts imageUrl and imageTag params to 
  define the tag.  The same task also pushes the image to the 
  registry. 
Some of the additional  notable features of this template include:
- Cloned repo is passed to subsequent Tasks using a Workspace. 
- Orders Tasks in a Pipeline using "runAfter" so that
  git-clone completes before we try to read from the Workspace 
  to find the Dockerfile and build an image.
- Uses a volumeClaimTemplate Volume as a Workspace.
- Uses a secret generated with config.json and mounts it 
  as a worksapce with name dockerconfig to provide registry 
  credentials. 
- Avoids hard-coded paths by using a Workspace's path
  variable instead.

I'm not sure what's causing this error or how to fix it. Can anyone help me troubleshoot this issue?

Thanks in advance!
