[BUG] 302 `httpx.HTTPStatusError` with 'https://app.phoenix.arize.com'

[enrico-stauss]

Describe the bug I was trying to use the hosted version of Arize Phoenix and it seemed to work with LlamaIndex instrumentation, but when using the px.Client directly I get the described error.

To Reproduce

1. Sign up to https://app.phoenix.arize.com/
2. Copy the API key
3. Execute

   import os
   import phoenix as px
   os.environ["OTEL_EXPORTER_OTLP_HEADERS"] = "api_key=<MY_API_KEY>"
   os.environ["PHOENIX_CLIENT_HEADERS"] = "api_key=<MY_API_KEY>"
   os.environ["PHOENIX_COLLECTOR_ENDPOINT"] = "https://app.phoenix.arize.com"
   client = px.Client(endpoint="https://app.phoenix.arize.com", api_key="<API_KEY>")
   client.get_spans_dataframe()
   # OR 
   dataset = client.get_dataset(id="<ID>", version_id="<VERSION_ID>")
   

4. Get

    Traceback (most recent call last):
        File "...\test.py", line 26, in <module>
            ds = client.get_spans_dataframe()
        File "...\site-packages\phoenix\session\data_extractor.py", line 46, in get_spans_dataframe
            self.query_spans(
        File "...\site-packages\phoenix\session\client.py", line 194, in query_spans
            response.raise_for_status()
        File "...\site-packages\httpx\_models.py", line 763, in raise_for_status
            raise HTTPStatusError(message, request=request, response=self)
    httpx.HTTPStatusError: Redirect response '302 Found' for url 'https://app.phoenix.arize.com/v1/spansproject_name=default&project-name=default'
    Redirect location: '/login'

I do hope you can reproduce the issue. I had the same problem with version 4.36.0 and tried to resolve by upgrading.

Environment:

• OS: Windows
• Version 5.0.0
