"Use via API" with Bash returns an incorrect file download path

[lilacs2039]

Describe the bug

When the gradio application that returns images is used via API with the curl command, the wrong image file download path is returned.

Reproduction

Run the following gradio application on a local server and execute the curl command. The incorrect file download path is returned. Accessing the download path returned by the browser yields "{"detail": "Not Found"}". The correct download path is "the path excluding the path string before /file".

App

app.py

import gradio as gr
from transformers import pipeline

pipe = pipeline(
    task="depth-estimation",
    model="depth-anything/Depth-Anything-V2-Small-hf",
)

def estimate_depth(image):
    return pipe(image)["depth"]

demo = gr.Interface(
    fn=estimate_depth,
    inputs=gr.Image(type="pil", label="Input Image"),
    outputs=gr.Image(type="pil", label="Estimated Depth"),
    examples=[
        [
            "https://raw.githubusercontent.com/gradio-app/gradio/main/test/test_files/bus.png"
        ]
    ],
    title="Depth Estimation",
)
if __name__ == "__main__":
    demo.launch(
        server_name="127.0.0.1",
        server_port=7870,
    )

Start Server

python app.py

Use via API

curl -X POST http://127.0.0.1:7870/call/predict -s -H "Content-Type: application/json" -d '{
  "data": [
    {"path":"https://raw.githubusercontent.com/gradio-app/gradio/main/test/test_files/bus.png"}

 | sed -n 's/^data: //p' | jq -r '.[0].url'

Interesting, so just to confirm, there's an extra "/c" in the returned path?

[lilacs2039]

there's an extra "/c" in the returned path?

It depends on the case. In this case there was a "/c", but in other cases it could have been "/call/est". (i.e., http://127.0.0.1:7869/call/est/file=/tmp/gradio/10.... .55/image.webp)

Found problem here too.

This space show a example using curl or PowerShell https://huggingface.co/spaces/rrg92/GradioApiBug
