No artifact has been found with name “AverageRatings”

[MarianKijewski]

After

• cloning the repository,
• creating the github auth token with read:packages permissions,
• running the npm install,
• and using cds watch

I get the following logs:

cds serve all --with-mocks --in-memory?                                                                                                                                              
( live reload enabled for browsers )

[WARNING] srv/mashup.cds:11:24-38: There is no definition in the model whose name starts with “ReviewsService.AverageRatings” (in using:“AverageRatings”)

I also saw this comment, under different issue which suggest using npm up, but I get the same error.
