How to use with LightLLM proxy

I would like to use sgpt with LightLLM proxy, but I only get this error:

```
Error: error, status code: 404, message: %!s(<nil>)
```

Any idea on what I'm doing wrong?
The config is this:

```
maxtokens: 2048
model: bedrock-claude-v3.7
temperature: "1"
topp: "1"
```
