cli: --output-format flag is not always honored

[lilioid]

Description

The --output-format flag is not always honored.
For example, if one runs a stackit ske cluster list -o json on a project that has SKE enabled but where no clusters yet exist, the CLI only outputs a plaintext error.
With the current behavior, it is not easily possible to use the STACKIT cli in scripts because one cannot always parse the output correctly.

Steps to reproduce

1. Run stackit ske cluster list --project-id=… -o json on a project where SKE is enabled but where no cluster has yet been created

Actual behavior

The CLI exits with exit code 0 (which is fine) and the following plaintext output:

No clusters found for project "…"

Expected behavior

The CLI should exit with code 0 and print [] to stdout.

Environment

• OS: Linux
• Version of STACKIT CLI (see stackit --version): v0.32.0

Hi @lilioid,
thank you for reporting this issue. We will have a look at it.

Hi @lilioid,

just wanted to let you know that we fixed this for SKE (a0eee4e) and we're working on fixing it for all other list commands also :)

Best regards

Hello! It seems this is also the case with stackit auth login - the -o flag does nothing there.

Hi @KevinGimbel,
what would be the expected result for you, when running $ stackit auth login with the output flag?

When you need the access token, you can also use $ stackit auth get-access-token -o json.

Best regards,
Marcel

I expected to get a credentials.json which i could store into a file -- I guess get-access-token is what I should be using instead!
