GCP Scanning - Unable to extract the selflink of the resource

I am trying to exctract the selflink for the GCP resources from into the output results, however, I am not able to extract it. Any pointers on how to include this self link into the output.
@matthewdfuller please help!

Start by tracing the GCP scanning path that builds the output results and identify where resource metadata is assembled. Confirm how the selflink is represented for each GCP resource, then verify that the selflink appears in the resulting output.
