ValueError: Error building node ChatOpenAI: 1 validation error for ChatOpenAI
__root__
Did not find openai_api_key, please add an environment variable `OPENAI_API_KEY` which contains it, or pass `openai_api_key` as a
named parameter. (type=value_error)
Same here, as well as "INFO: 127.0.0.1:58114 - "POST /validate/node/dndnode_85 HTTP/1.1" 500 Internal Server Error" When I put the openAI key in the LLM box, then the erros stop, but when I try to chat nothing happens and the terminal goes in a non-stop printing of "WARNING: Invalid HTTP request received.".
Perhaps comparing with "production" will make it compatible with local run. But when I run with NODE_ENV=development I'm still having issues.
With 0.68 release, the chat is working for me now, without the "invalid HTTP request received" in terminal. The rest is the same.
@ATL64 Could you point out another specific issue apart from reloading past flows?
OP posted a terminal output of python errors.
have a read of what its' telling you:
Did not find openai_api_key, please add an environment variable `OPENAI_API_KEY` which contains it, or pass `openai_api_key` as a named parameter.
so I launch it like this:
start.sh
OPENAI_API_KEY=paste-your-key-here \
python -m langflow
then make that executable:
chmod +x ./start.sh
then anytime you want to launch it:
./start.sh
