How can I get st.text_area to output a properly formatted URL?

Using Streamlit
, ,
1

Hello,

I am trying to pass a url or list of urls to Firecrawl for scraping using st.text_area, but I am getting the following error message (full traceback at the bottom:

HTTPError: Unexpected error during scrape URL: Status code 400. Bad Request - [{'code': 'custom', 'message': 'URL must have a valid top-level domain or be a valid path', 'path': ['url']}]

The relevant code (as the app is not deployed) is:

urls = []
        urls_input = (st.text_area("Input one or more urls separated by commas"))
        for url in urls_input:
            urls.append(url)

If I simply code in a url list and pass that to the Firecrawl loader it works just fine so I know that’s not the issue. What type of object does the st.text_area create, and what format is it in?

Any help is greatly appreciated!

It returns a string or None (see st.text_area - Streamlit Docs).

Iterating over that string means getting each character individually. You probably meant to split that string first based on the commas.
