[sdk] enable_caching breaks when using CreatePVC: must specify FingerPrint

[TobiasGoerke]

Environment

• KFP version:
  2.0.3 (manifests v1.8 release)
• KFP SDK version:

kfp                      2.4.0
kfp-kubernetes           1.0.0
kfp-pipeline-spec        0.2.2
kfp-server-api           2.0.3

Steps to reproduce

Given the following example:

from kfp import dsl
from kfp import kubernetes


@dsl.component
def test_step():
    print("Hello world")


@dsl.pipeline
def test_pipeline():
    kubernetes.CreatePVC(
        access_modes=["ReadWriteOnce"],
        size="10Mi",
        storage_class_name="default",
    )
    test_step()


client.create_run_from_pipeline_func(test_pipeline, arguments={}, enable_caching=False)

The pipeline will fail. Note the enable_caching, which will cause the issue when set to False.

We will see an error in the created PVC step:

F1031 14:29:54.216337 27 main.go:76] KFP driver: driver.Container(pipelineName=test-pipeline, runID=02ad61d6-8b9b-47a7-b626-0d65f3838b42, task="createpvc", component="comp-createpvc", dagExecutionID=9094, componentSpec) failed: failed to create PVC and publish execution createpvc: failed to create cache entrty for create pvc: failed to create task: rpc error: code = InvalidArgument desc = Failed to create a new task due to validation error: Invalid input error: Invalid task: must specify FingerPrint

@TobiasGoerke what is the version of your KFP runtime? Maybe there is a bug when resolving cache key in the PVC creation operation. cc @chensun to learn more.

I'm on manifests/v1.8-branch, i.e. 2.0.3.

I am also facing the exactly same issue with the same output on KFP backend 2.0.3 with Kubeflow 1.8.0 manifests deployment.
The PVC is created, but the component reported the error from the logs and exist with error.

Just want to add some additional info. After experiencing this issue, kfp backend didn't work anymore in my case.
I have to restart all the deployments kubectl -n kubeflow rollout restart deployments to be able to run v2 pipeline again.

With the api-server 2.0.5 with enable_caching=False, this issue still exists.

• KFP Backend API-SERVER version:
  2.0.5 (manifests v1.8 release modified)
• KFP SDK version:

kfp                      2.4.0
kfp-kubernetes           1.0.0
kfp-pipeline-spec        0.2.2
kfp-server-api           2.0.5

• KFP SDK version:

kfp                      2.4.0

kfp-pipeline-spec        0.2.2
kfp-server-api           2.0.5

@yingding finally, it's working fine?

[yingding]

@kabartay Unfortunately, this issue still exists, even with

• KFP Backend API-SERVER version:
  2.0.5 (manifests v1.8 release modified)
• KFP SDK version:

kfp                           2.6.0
kfp-kubernetes                1.1.0
kfp-pipeline-spec             0.3.0
kfp-server-api                2.0.5

Hopefully, it can be resolved in the next KFP backend API SERVER.
