Unhandled error when trying to debug from IDX

[jmiller-pwi]

Description:

Encountered an unhandled error in the injected client.js script while debugging a Flutter application in Google IDX, with the Google Chrome web browser. The error message suggests a SecurityError, stating that the construction of a WebSocket failed due to attempting to initiate an insecure connection from a page loaded over HTTPS.

IDX version: 1.83.1
Chrome version: 125.0.6422.142

Steps to Reproduce:

1. Start debugging a Flutter application in Google IDX.
2. Monitor the console output for any errors.
3. Observe the error related to the construction of a WebSocket and the SecurityError message.

Expected Behavior:

Debugging should proceed smoothly without encountering any unhandled errors related to WebSocket construction.

Actual Behavior:

Encountered an unhandled error in the injected client.js script, specifically related to WebSocket construction and SecurityError.

Additional Information:

The error message suggests that disabling the injected client.js script using the --no-injected-client flag in webdev might resolve the issue, but it would also disable debugging and hot reload/restart functionality.

SecurityError: Failed to construct 'WebSocket': An insecure WebSocket connection may not be initiated from a page loaded over HTTPS.
