Unable to Run Flow Without Chat Input component via API

Description

I am trying to execute a flow using the Langflow API, but I noticed that the API endpoint only triggers the Chat Input component. My flow does not include a Chat Input component, yet I still want to execute it through the API.

Expected Behavior

I should be able to run a flow via the API even if it does not contain a Chat Input component.

Actual Behavior

The API only seems to execute flows that contain a Chat Input component, making it unclear how to trigger flows that use other input components.

Steps to Reproduce

1. Create a flow without a Chat Input component.
2. Attempt to run it using the API.
3. Observe that the flow is not executed properly.

Question

How can I execute a flow via the API that does not include a Chat Input component?

To execute a flow via the Langflow API that does not include a Chat Input component, you can use the /run/advanced/{flow_id} endpoint. This endpoint allows you to execute flows without requiring a Chat Input component. You simply need to provide the flow_id of the flow you want to execute. The inputs parameter is optional and defaults to an empty list, so you can omit it or provide an empty list if no specific input components are required. Here's an example of how you might call this endpoint:

import requests

url = "http://your-langflow-server/api/v1/run/advanced/{flow_id}"
headers = {
    "Authorization": "Bearer YOUR_API_KEY"
}

response = requests.post(url, headers=headers)
print(response.json())

Replace {flow_id} with the actual ID of the flow you want to execute and YOUR_API_KEY with your API key. This will execute the flow without any specific Chat Input component ^[1].

@dosu
`
import requests

url = "http://0.0.0.0:7860/api/v1/run/advanced/{flow_id}"
headers = {
"Content-Type": "application/json"
}

response = requests.post(url, headers=headers)
print(response.json())
`

This code doesnt work. I dont have an API Key or Bearer authorization
Here's the response that I get
{'detail': [{'type': 'uuid_parsing', 'loc': ['path', 'flow_id'], 'msg': 'Input should be a valid UUID, invalid character: expected an optional prefix ofurn:uuid:followed by [0-9a-fA-F-], foundlat 3', 'input': '{flow_id}', 'ctx': {'error': 'invalid character: expected an optional prefix ofurn:uuid:followed by [0-9a-fA-F-], foundlat 3'}}]}

The error message indicates that the flow_id you are using is not in the correct UUID format. Make sure to replace {flow_id} in the URL with the actual UUID of the flow you want to execute. The UUID should be a valid string of characters in the format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, where each x is a hexadecimal digit ^[1][2].

Additionally, since you mentioned not having an API key or Bearer authorization, you might need to check if the API requires authentication. If it does, you will need to obtain the necessary credentials to access the endpoint.
