Having Problem registering anthropic Models on Llama-Stack

[mansiUnifynd]

I’ve been trying to register Anthropic models, but every time I add one it says the model isn’t supported.
Could someone please guide me on how to properly register Anthropic models on Llama Stack? It would be a great help.
Heres the list of things I have done:

1. I have update the API Key in my run.yaml
   - provider_id: anthropic
   provider_type: remote::anthropic
   config:
   api_key: ${env.ANTHROPIC_API_KEY:""}

2. Below is the command that i am using to register the model:
   llama-stack-client models register claude-3-5-sonnet --provider-id anthropic --provider-model-id claude-3-5-sonnet-latest --metadata {} --model-type llm

ERROR I AM GETTING:
INFO:httpx:HTTP Request: POST http://localhost:8321/v1/models "HTTP/1.1 400 Bad Request"
╭─────────────────────────────────────────────────────────────────────────────────────────────────────╮

check which models Anthropic's model listing endpoint (https://api.anthropic.com/v1/models) is advertising.

$ uv run --with llama-stack-client llama-stack-client models list

you can use anything in the provider_resource_id column.
