Empty HTML and text responses from web scraping

Manus's thoughts: It appears that I am currently unable to retrieve any meaningful content from website, as both the HTML and text responses are empty.

I get the above error after the process gets completed. Even for the sample prompt that is given in the repo, the scraping content is empty.

I followed the steps explained below.

1. Cloned the github repository using uv (recommended) as shown in the repo
2. Installed all the dependencies as mentioned in the requirements.txt file
3. Also installed playwright module
4. Modified the config file with the essential LLM keys (OpenAI - gpt-4o-mini) and values
5. Run the main.py file and gave the prompt

The steps got executed orderly but the web scraping did not happen properly. Everytime I run the script, for every prompt that I give, the Manus's thoughts is the same : Unable to retrieve any meaningful content from the website, as both the HTML and text responses are empty. and the final result will be some generalised response from the LLM. Even for the sample prompt given in the repo, I'm getting the same response.

What is the solution to this? Is there any step that I missed to perform? Please guide me through the process.

Thank you in advance!
