Fixing Error “Azure OpenAI API instance name not found”

When using the Azure OpenAI API with the LangChain library, we will receive the error “Azure OpenAI API instance name not found”. It often shows that the setup name provided in the AzureOpenAI class does not match the name of the Azure OpenAI model. This error may occur for a variety of reasons. Here are possible causes and their respective fixes:

1. The issue may occur due to an incorrect or invalid OpenAI API key.

Fix: Make sure we have the correct and valid OpenAI API key in the environment variables or.env files.

2. The environment variables used for the OpenAI API setup may be missing or wrongly set.

Fix: Double-check and correctly setup those environment variables.

3. The issue could be linked to the way it works of the OpenAIEmbeddings class, which is included in the langchain/embeddings/openai module.

Fix: To fix any issue with the class implementation, we must check the langchain/embeddings/openai module’s documentation or source code.

4. Having many OpenAI keys in a global environment can cause issues.

Fix: Make sure there are no conflicting OpenAI keys defined globally and that just the right key is set up in the local environment file.

5. The “deployment_name” option should exactly match the name of the Azure OpenAI model we’ve deployed, including capitalization and spacing. Otherwise, it may lead to errors.

Fix: Double-check the deployment name in Azure OpenAI Studio to confirm it matches the one used in the code.
