Error submitting workflow via argo cli when passing --parameter-file flag

Checklist

• Double-checked my configuration.
• Tested using the latest version.
• Used the Emissary executor.

Summary

What happened/what you expected to happen?
Connected to the Argo server API by setting the environment variables found in the User Info section of the Argo Workflows UI.

Attempted to submit a Workflow from an existing WorkflowTemplate:
argo --loglevel debug submit --from wftmpl/deployment-workflow-template -n argo --parameter-file deploy-config.yaml

Logs below showing evidence of:

• successful connection to Argo server API
• ability to submit a Workflow when not using the --parameter-file flag

I've omitted the server URL and port.

argo-workflows-server log entry:

time="2022-03-15T22:01:29.154Z" level=error msg="finished unary call with code Unknown" error="open deploy-config.yaml: no such file or directory" grpc.code=Unknown grpc.method=SubmitWorkflow grpc.service=workflow.WorkflowService grpc.start_time="2022-03-15T22:01:29Z" grpc.time_ms=14.878 span.kind=server system=grpc

The commands above are executed in a GitLab runner container. When I run the same command locally - connecting via the k8s API server with no ARGO env vars set, it succeeds.

The deploy-config.yaml exists and the file permissions are fine, so I am unsure as to the origin of the error. Further, it's odd that this does not occur in the case mentioned above.

What version are you running?
v3.3.0, this behaviour also occurs in v3.2.9

@asaunders57 Can you try without argo server? looks like the file is not able in your current folder/doesn't have permission to open it.

There is a bug here that could have been a security issue. When submitting via the server, the parameter file is read, but is read from the server file-system. Luckily --parameter-file=/etc/passwd would not work. I'm going to raise a PR to fix this.
