Unable to configure containerImage in Hugo preview pipeline

In the api-spec-host project, an update is being created that moves the current code to use NodeJS instead of Shell for the build script, as well as some minor updates for new features that required a few changes to the Hugo layouts. Locally I had no problems running this code, but upstream the latest hugo-node image uses Hugo 0.76.5 rather than 0.110.0 which is what we have been switching to.

In an attempt to fix this, I updated the image used in the build using the containerImage property, setting it to our Hugo 110 + Node 18 build. With this change set, the build fails at start when loading the configurations. I've included the message below, as well as a link to the changed file, and the failing build. If I should be using a different property please let me know! I did my best to find the best one but I'm not versed in Groovy syntax

Failing build: https://foundation.eclipse.org/ci/webdev/job/eclipsefdn-spec-host/job/MR-5/16/console
