'generator' object does not support the context manager protocol

[miagi-quyenhn]

Currently I'm having an error when updating crewai from version 0.30.11 to 0.35.0 included with the packages (langchain-openai, embedchain). When running crew.kickoff(), the error 'generator' object does not support the context manager protocol will appear. If anyone has any suggestions to help me resolve this bug, please leave a comment. Thank you!

Environment information: crewai==0.30.11 => 0.35.0 crewai-tools==0.2.6 => 0.4.0 langchain-openai==0.0.5 => 0.1.7 embedchain==0.1.102 => 0.1.109

Can you try the latest version crewai-0.35.8, let us know if still an issue

Hi @theCyberTech , I upgraded crewai to 0.35.8 but the error still occurs, maybe the problem lies in langchain-openai when using chainlit + crewAI application, do you have any suggestions for me?

[miagi-quyenhn]

It's agentops. That's the problem.

self.logger.debug('get api key.AgentOps')
agentops_api_key = os.environ['AGENTOPS_API_KEY']
self.logger.debug('AgentOps initialise')
agentops.init(agentops_api_key)
agentops.start_session()  
self.logger.info('crew kickoff start')
self.result = crew.kickoff()
self.logger.info('crew kickoff end')
self.logger.debug('AgentOps terminate')
agentops.end_session("Success")

Removing agentops helps eliminate this error!

I'm having the same problem.. AgentOps doesn't work anymore with CrewAI, but i don't know if the problem is from AgentOps or from CrewAI. Please help because AgentOPS is essential
