There is an issue with the sign-in flow in the v1.4 of the Amazon Q Developer extension release last night. This only impacts Code Server used in the workshop and does not impact the desktop version. To revert to v1.3, run the following script in the Code Server terminal. sudo rm -f /tmp/AmazonWebServices.amazon-q-vscode.vsix Q_URL=https://github.com/aws/aws-toolkit-vscode/releases/download/amazonq/v1.3.0/amazon-q-vscode-1.3.0.vsix curl -fsSL $Q_URL -o /tmp/AmazonWebServices.amazon-q-vscode.vsix sudo -u ubuntu --login code-server --install-extension /tmp/AmazonWebServices.amazon-q-vscode.vsix --force
