Error in empty project

The plugin gives an error in a basic empty project.
This popup opens when you expand the "Bazel build targets"
(All the folders are empty at this point)

Reproduce the issue in a basic empty project by expanding the "Bazel build targets" view while the folders are empty. Use the resulting popup and its error details to locate the affected extension entry point; done means the view opens without an error in an empty project.
