profile get --json exits 0 with no output

[marythought]

Description

otdfctl profile get <name> --json (or otdfctl --json profile get <name>) exits with code 0 but produces no stdout output.

Steps to Reproduce

otdfctl profile create my-profile https://platform.opentdf.local:8443
otdfctl profile get my-profile --json
# or
otdfctl --json profile get my-profile

Current Behavior

• Exit code: 0
• Stdout: empty

Expected Behavior

Either:

• Valid JSON output representing the profile, or
• A non-zero exit code with an error message if JSON rendering is not supported for this command

Why It Matters

Exit 0 + empty stdout is indistinguishable from "this profile has no data." Any script or tool that relies on --json output from profile get will silently get nothing, which is harder to debug than an explicit error. It also means the --json flag is effectively broken for this command.
