My extension uses vscode.Uri.file to construct a resource with a file path:

treeItem.resourceUri = new vscode.Uri.file( node.fsPath );

https://code.visualstudio.com/api/references/vscode-api#Uri

This works correctly in the stable build, but in the insiders build (1.32.0-insider, 7d0c9e6 ) I get the error:

vscode.Uri.file is not a constructor

Am I doing something wrong?
