Greptile Summary

This PR makes a single but important configuration change to the wand-generate API endpoint by switching its runtime from 'edge' to 'nodejs'. The wand-generate API is responsible for AI content generation using OpenAI/Azure OpenAI integration, supporting both streaming and non-streaming response modes.

The edge runtime in Next.js is designed for lightweight, fast-executing functions with limited Node.js API access, optimized for simple operations that can run at the edge of the network. However, the wand-generate API requires several Node.js-specific features that are either restricted or incompatible with the edge runtime:

• AbortController with setTimeout for managing streaming timeouts
• crypto.randomUUID() for generating unique request identifiers
• Complex ReadableStream operations for handling AI response streaming
• Long-running operations for AI content generation

By switching to the nodejs runtime, the API gains full access to Node.js APIs and can handle these operations reliably. This change ensures the wand functionality works properly within the broader Sim platform's workflow automation system, where AI-powered content generation is likely a critical feature for users building automated workflows.

Confidence score: 5/5

• This PR is extremely safe to merge with virtually no risk of breaking existing functionality
• Score reflects a simple, well-understood configuration change that addresses clear compatibility issues without modifying business logic
• No files require special attention as this is a single-line configuration change
