We are having problems building anything using Unity Cloud Build at the moment.
Even building from the same commit as earlier (build OK) generate this error.
Then more errors around “Asset folder not found” are being thrown even if the checkout earlier states that there is a big Asset folder.
I am having this same issue. I am able to select [Assets->Reimport] and I can see my assets, but as soon as the automatic refresh is triggered, the “error getting directory contents Assets/” shows up in the log, and any Assets are gone from the editor.
