To extend the timeout for the Langflow process and allow Playwright to execute for more than 30 seconds, you can adjust the timeout settings in both the Playwright configuration and the server-side process.

1. Playwright Configuration: In the playwright.config.ts file, increase the timeout setting. It's currently set to 120 seconds (120,000 milliseconds), but you can increase it further if needed. For example, to set it to 5 minutes:

   timeout: 300 * 1000,

2. Server-Side Process: The timeout for the server-side process is configured in the src/backend/langflow/__main__.py file. The default worker timeout is set to 300 seconds. You can adjust this by setting the LANGFLOW_WORKER_TIMEOUT environment variable to a higher value if necessary.

   timeout: int = typer.Option(300, help="Worker timeout in seconds."),

   You can set the LANGFLOW_WORKER_TIMEOUT environment variable in your terminal or import it from a .env file to change the default timeout.

These adjustments should help prevent the network error by allowing more time for the process to complete ^[1][2].
