How to resolve a 'Network Error' while accessing a database or while making API requests.

Problem Statement:

Users experience a "Network Error" message when Accessing the database or making API requests from Virtuoso due to Cross-Origin Resource Sharing (CORS) policies.

Solution:

To resolve the "Network Error" encountered during accessing the database or making API requests from Virtuoso, follow these steps:

Solution 1: Navigating to the Same Domain

1. Before accessing the database or making an API request, add a navigation step to the same domain to establish a secure connection with the server.
2. By doing this, you ensure compliance with Cross-Origin Resource Sharing (CORS) policies, guaranteeing that requests originate from the same origin. This effectively resolves CORS-related errors.
3. This method maintains the security of the Same-Origin Policy while accessing resources within the same domain, preserving the integrity of your operations.
   
   
   

Solution 2: Disabling Same-Origin Policy

1. Alternatively, disable the Same-Origin Policy to remove restrictions on cross-origin requests. This can resolve CORS-related errors and facilitate successful database access or API requests.
2. However, be aware that this approach can introduce security vulnerabilities due to unrestricted access to resources from various origins. Use this method with caution and only when necessary.
