When does this happen?
IF DelegateWorkToolSchema validation fails because the manager LLM passes dictionary objects instead of plain strings for the 'task' and 'context' parameters when delegating tasks in a CrewAI hierarchical process.
How others solved it
THEN Use a more capable LLM (e.g., gpt-4o instead of gpt-4o-mini) as the manager model. Configure the manager_llm parameter in the Crew object with a model known to produce correct string arguments, for example: ChatOpenAI(model_name='gpt-4o').
# Instead of: manager_llm=ChatOpenAI(temperature=0.1, model_name='gpt-4o-mini') manager_llm=ChatOpenAI(temperature=0.1, model_name='gpt-4o')
