What happened?

The get "prompts.get" returns an HTTP 404 when the prompt doesn't exist. It should be a clear prompt doesn't exist issue and not a HTTP 404.

Given it was my first use of prompt API, I thought I had connectivity issues and spent time looking at HTTP endpoint.

Example with a prompt that exists:

What did you expect to happen?

I expect a clear Message that the prompt doesn't exist, shouldn't be a python & HTTP error

How can we reproduce the bug?

Run this on Phoenix Cloud.
from phoenix.client import Client

Initialize a phoenix client with your phoenix endpoint

By default it will read from your environment variables

cl = Client(

endpoint="https://my-phoenix.com",

)

Pulling a prompt by name

prompt_name2 = "article-bullet-summarizer-random"
cl.prompts.get(prompt_identifier=prompt_name)

This makes sense. We can wrap errors in the client with our own set of errors.
