Assistance Required: Shopify Page Speed and Facebook App Error

[StanwellsKIds]

Hello Team,

We have encountered an error with our Shopify page speed. When we try to test it, the following error is displayed:
"Browser errors were logged to the console (WebSocket connection to 'ws://localhost:12387/' failed: Error in connection establishment: net::ERR_NOT_IMPLEMENTED)."

Additionally, we are facing an issue related to Facebook integration. Could you kindly assist in resolving these errors?
