[API] Get apis/v1beta1/runs/${run-id} didn't get the full status, if custom task was defined in the pipeline

[fenglixa]

/kind bug

What steps did you take and what happened:
[A clear and concise description of what the bug is.]

1. Run a PR which with custom task defined inside via kfp UI.
2. Call GET apis/v1beta1/runs/${run-id} didn't get the full result of this run.

What did you expect to happen:
Call GET apis/v1beta1/runs/${run-id} should get the complete result of this run

Additional information:
[Miscellaneous information that will assist in solving the issue.]

Environment:

• Python Version (use python --version):
• SDK Version:
• Tekton Version (use tkn version):
• Kubernetes Version (use kubectl version):
• OS (e.g. from /etc/os-release):

@Tomcli , do you know who is familar with this issue?

[Tomcli]

Right now, the Get apis/v1beta1/runs/${run-id} only returns the pipelinerun spec which doesn't include the pipeline loop spec due to tektoncd/pipeline#3682

[Tomcli]

Although we can make the api to do some extra api calls for getting the custom task crd, but it will need to alter the api spec and it could add some extra workloads to the etcd and loop controller. Maybe I can make it as an experimental feature for now so people can opt-out if they don't want to decrease performance.

[Tomcli]

Oh i think this also requires to alter the database schema since we need a place to store the custom task crd...

[fenglixa]

Thanks @Tomcli, this issue is not related to TaskSpec defination for custom task.
When get the PipelineRun status via this API. It returned the custom task CR result but not the pipelinerun result. That's why the issue logged.

[Tomcli]

@fenglixa sorry i couldn't reproduce this issue. I believe you also use kfp-tekton 0.7? In kfp-tekton 0.7 with custom task, this is what i get from the runs api. It returns the PipelineRun CR result. The runs status is under status.run. and regular task status is under status.taskruns.

[Udiknedormin]

@fenglixa @Tomcli What is the status of this issue?

[Tomcli]

@Udiknedormin @fenglixa for getting all the information in one pipelinerun yaml, I have a PR over here #512 (need to fix some tests)

@fenglixa do you have an example that can reproduce this issue? Do you see it when the pipeline is running or completed?

[fenglixa]

Based on comments from Tomcli, I am worried the api-server is an old one in my cluster caused this issue.
@Udiknedormin, which version of kfp-tekton are you using, you reproduced this issue, right?
