[bug]: Registry ID Validation (Proxy Cache)

Assessment

Research direction

Description

Description

When creating a Proxy Cache project, the CLI fails to validate the --registry-id flag. If a non-numeric value is provided, the error is ignored, and the project creation proceeds with a registryID of 0, which can lead to incorrect project configurations or unexpected server errors.

Steps to Reproduce

1. Run the command: harbor project create my-proxy --proxy-cache --registry-id "my-registry"
2. Observe the output: "Project created successfully" (even though the Registry ID was invalid).

Expected Behavior

The CLI should validate that the --registry-id is a valid integer before making the API request and return an error if it is not.

Actual Behavior

The parsing failure is ignored, and a value of 0 is sent to the Harbor API.

Environment

• OS: Any
• Tool version: Latest main branch
• Other relevant details: Affects logic in pkg/api/project_handler.go line 34.

Additional Context

proof:

as you can see it should've stopped at "abc"
