@louisLiu1004 Hello there! I'm here to assist you with bug fixes, questions, and contributing to the project. Let's work together to resolve any issues you encounter while waiting for a human maintainer.

I found a similar discussion regarding the JSON parsing error "Expecting value: line 1 column 1 (char 0)" when using the Firecrawl tool ^[1].

To resolve this issue, ensure that the server response is not empty before parsing it as JSON. You can modify the _post_request and _get_request methods to check if the response content is not empty:

def _post_request(self, url, data, headers, retries=3, backoff_factor=0.5):
    for attempt in range(retries):
        response = requests.post(url, headers=headers, json=data)
        if response.status_code == 502:
            time.sleep(backoff_factor * (2**attempt))
        else:
            if response.content:  # Check if response is not empty
                return response
            else:
                raise ValueError("Empty response received")
    return response

def _get_request(self, url, headers, retries=3, backoff_factor=0.5):
    for attempt in range(retries):
        response = requests.get(url, headers=headers)
        if response.status_code == 502:
            time.sleep(backoff_factor * (2**attempt))
        else:
            if response.content:  # Check if response is not empty
                return response
            else:
                raise ValueError("Empty response received")
    return response

This should help prevent the JSON parsing error by handling cases where the server returns an empty response ^[2][3].

I have the same issue. Currently I use JinaReader instead at this moment.
It seems to be not reproduced in Cloud version.

can't reproduce, I also use a self-host firecrawl, it works well

@hjlarry So any suggestions?

I think you can try the scrape tool of firecrawl first, because it is simpler than the crawl tool.
if it not works, try to debug this line to check what is the response
the firecrawl also supply admin panel http://localhost:3002/admin/@/queues, you can get more information here.

do u self-host firecrawl in your computer or in the service, it works well when i self-hosted in my computer,but once i publish it on the service, it won't work

dify just send a simple http request to the firecrawl server, so the key point to solve this issue is to check what's the response of this request from dify's api server
