Quick Fix: To resolve this error in Vercel with Azure, ensure you have set the environment variable OPENAI_API_KEY with your valid OpenAI API key. This key can be obtained from your OpenAI account dashboard.
The Problem:
I implemented openAI API in my Next.js app with the help of langchain library and it works locally, but in Vercel (ProVersion) it throws an error:
> Error: (Azure) OpenAI API key not found
> at new OpenAIChat (file:///var/task/node_modules/langchain/dist/llms/openai-chat.js:184:19)
> at new OpenAI (file:///var/task/node_modules/langchain/dist/llms/openai.js:54:20)
> at /var/task/.next/server/pages/api/tasks/ai.js:63:21
> RequestId: 472c0bdb-dbbc-4cd4-95a3-1808d0b6a5ac Error: Runtime exited with error: exit status 1
> Runtime.ExitError
I put OPENAI_API_KEY environmental variable (identical to the one in my .env file) in Vercel and load the API key in my backend, but it still doesn’t work in Vercel.
The Solutions:
Solution 1: Environment Variable Naming
Ensure that the environment variable you’ve set in Vercel exactly matches the name of the environment variable expected by the langchain library. In this case, make sure it’s named “OPENAI_API_KEY”, and not “AZURE_OPENAI_API_KEY”.
Solution 2: Set the Environment Variable Correctly
Ensure you properly set the environment variable, OPENAI_API_KEY, in Vercel. Delete the existing variable, create a new one with the correct value, and redeploy your project. This ensures that Vercel has the necessary API key to interact with OpenAI.
Q&A
