Sprig Functions don't work on dataKey or contextKey

Input Type: GitHub webhook
Content-type: application/json

I am trying to extract substrings from inputs to make searching via labels easier; for example I am trying to get the branch name, standardize it, and use it as a metadata label. The same can be said for extracting the Git Commit short hash.

Describe the solution you'd like
dataKey can use Spring functions.
e.g.

          parameters:
            - src:
                dependencyName: test-dep
                dataKey: body.head_commit.id | substr 0 7
              dest: metadata.labels.commit-id

Describe alternatives you've considered
There aren't any other options.

For example:

          parameters:
            - src:
                dependencyName: test-dep
                dataTemplate: "{{ body.head_commit.id | substr 0 7 }}"
              dest: metadata.labels.commit-id

Does not work, nor removing the leading and trailing spaces from the Sprig template.

This also fails with:

dataTemplate: "{{ .Input.body.head_commit.id | substr 0 7 }}"
