Updating the task1 definition to use the correct attribute name should resolve the issue:

task1 = Task( description="""Conduct a comprehensive analysis of the latest advancements in AI in 2024. Identify key trends, breakthrough technologies, and potential industry impacts. Compile your findings in a detailed report. Your final answer MUST be a full analysis report""", agent=researcher # <-- Corrected attribute name here )
