To Reproduce
Use the python package gpt-researcher==0.13.4 (latest release - June 1)

researcher = GPTResearcher(
            query=query, 
            report_type=report_type,
            report_source="hybrid",
            source_urls=sources, 
            complement_source_urls=complement_sources
        )
        
researcher.set_verbose(self.verbose)
await researcher.conduct_research()
report = await researcher.write_report() 

But on looking at the logs I see a lot of the ScrapeResponse errors as mentioned above.
I have manually verified that these links are able to be scraped by Firecrawl independently.
