400 Bad Request - exploding OCI artifact resource blob

[hilmarf]

What happened:

Create the file: docker-hello-tiny.yaml with the following content:

components:
- name: docker.io/recmo/docker-hello-tiny
  version: v1.0
  provider:
    name: recmo
  resources:
  - name: docker-hello-tiny
    version: v1.0
    type: ociImage
    access:
      type: ociArtifact
      imageReference: docker.io/recmo/docker-hello-tiny:latest

Then execute the two ocm commands:

ocm add componentversions --create --file docker-hello-tiny docker-hello-tiny.yaml
ocm transfer componentversions --copy-resources docker-hello-tiny 371000008081-20241028-09281372-787.staging-dev.repositories.cloud.sap --uploader 'ocm/ociArtifacts={"ociRef":"371000008081-20241028-09281372-787.staging-dev.repositories.cloud.sap/images"}'

Which fails with:

What you expected to happen:

The image gets pushed to the target repository.

How to reproduce it (as minimally and precisely as possible):

See above.

Anything else we need to know:

Credentials are required for the target repo.

I suggest we add more debug information on request details, since 400 alone in this case is not enough to reproduce.
