Render function error lacks filename

[sttts]

Replacing crossplane/crossplane#5250.

What happened?

crossplane-cli-v1.14.5 beta render cluster/local/composition-render/mxp-control-plane/kube-control-plane/vcluster/xr.yaml cluster/xpkgs/mxp-control-plane/kube-control-plane/vcluster/composition.yaml cluster/local/composition-render/functions.yaml -o cluster/local/composition-render/mxp-control-plane/kube-control-plane/vcluster/observed.yaml

gives this output:

crossplane: error: cannot render composite resource: pipeline step "render-composed-resources" returned a fatal result: invalid function input: cannot parse the provided templates: template: manifests:606: bad character U+005B '['

The output does not say which manifest.

How can we reproduce it?

With the commands above and some template with a go-template error.

What environment did it happen in?

Crossplane version: 1.14.5
