Using UI can't choose a source for the new dashboard #718
Description
For started pipeline, after creating a new dashboard, it isn't available to add the source when trying to add a widget.
This has happened multiple times, but now, after clearing all the data, the bug is still present.
The pipeline is most straightforward as possible Machine data adapter and data sink.
