"mapping values are not allowed in this context" when adding valid crd dependency

[eric-carlsson]

What happened?

When attempting to add a dependency for VPA CRDs, I got

crossplane: error: failed to parse file "vpa-v1-crd-gen.yaml": error converting YAML to JSON: yaml: line 47: mapping values are not allowed in this context

Line 47 looks like

              More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status.

as part of a description field:

            description: |-
              Specification of the checkpoint.
              More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status.

This line is valid yaml since it's in a block scalar, but it seems like it's incorrectly parsed as a field of its own.

How can we reproduce it?

crossplane dependency add https://github.com/kubernetes/autoscaler/blob/vertical-pod-autoscaler-1.6.0/vertical-pod-autoscaler/deploy/vpa-v1-crd-gen.yaml

What environment did it happen in?

• Crossplane CLI version: v2.5.0
• Platform (e.g., linux/amd64): darwin/arm64

Same issue when adding Gateway API CRDs:

$> crossplane dependency add https://github.com/kubernetes-sigs/gateway-api/blob/main/config/crd/standard/gateway.networking.k8s.io_gateways.yaml
✗ Adding https://github.com/kubernetes-sigs/gateway-api/blob/main/config/crd/standard/gateway.networking.k8s.io_gateways.yaml
crossplane: error: failed to parse file "gateway.networking.k8s.io_gateways.yaml": error converting YAML to JSON: yaml: line 47: mapping values are not allowed in this context

Edit:

Adding it as a Git dependency does work, however:

crossplane dependency add https://github.com/kubernetes-sigs/gateway-api/ --git-ref=main --git-path=config/crd/standard
