Node.JS Troubleshooting

Thank you for reaching out to Pinecone. Our Pinecone Node.js client is in Public beta with limited support. This case appears to be a configuration issue and not a bug or defect within the product. There could be several reasons why a Node.js application works in development mode but not in deployment. Here are a few possibilities:
 

1. Dependency version mismatch: Sometimes, different environments have different versions of dependencies installed. If the application was developed using a specific version of a dependency, and that version is not installed on the deployment environment, the application may not work as expected.
2. Environment configuration: The development environment may have different configurations from the deployment environment. For example, the development environment may have different environment variables set or different network settings. If the application relies on specific configuration settings that are not present in the deployment environment, it may not work.
3. Permissions: The application may require permissions to access certain resources that are only granted in the development environment. For example, if the application needs to write to a specific directory, the permissions to write to that directory may only be granted in the development environment.
4. Database connection: If the application relies on a database connection, it's possible that the connection settings are different in the deployment environment. For example, the database may have a different hostname or port number.
5. Code optimization: During development, the application may have been running on a development server that did not optimize the code. However, when deployed, the application may be running on a production server that is optimized for performance. If there are code issues or performance bottlenecks, they may only appear when the application is deployed.
6. It may be necessary to install the fetch python library for compatibility with node.js

In order to troubleshoot the issue, it's important to identify where the application is failing and compare the development and deployment environments to see what differences exist. It's also important to review any error messages or logs that are generated to help identify the issue.
