Explanation of the problem

This issue is related to the GitGraph extension in Microsoft Visual Studio Code (VS Code). The issue is reported to occur when using VS Code version 1.57.0, and it is stated that the problem does not occur when all extensions are disabled. The environment in which the issue is reported includes the VS Code version, commit, and date, as well as the versions of Electron, Chrome, Node.js, V8, and the operating system and version (Linux x64 and Ubuntu 21.04).

The reproduction steps indicate that the issue occurs after updating to VS Code version 1.57. The GitGraph extension stops working and the following error message is displayed in the extension: “Error loading webview: Error: Could not register service workers: InvalidStateError: Failed to register a ServiceWorker: The document is in an invalid state.” This error message suggests that there may be an issue with the service worker registration process and that the document may be in an invalid state. It is likely that this issue is specific to the GitGraph extension and may not affect other extensions or functionality within VS Code.
