1 year ago Root cause:
- Unit tests randomly generate the count matrix for test runs of the census build/validate methods
- In the case where any cell has no counts > 0 (i.e., nnz==0 for that cell), the builder will incorrectly calculate a number of axis stats
- and the unit test will fail
The CxG schema 3.1.0 does not specify behavior in this case, implying that it is legal. However, there is no obvious use case, and no data currently the CxG corpus with this condition.

Usually, when manually re-run this GHA succeeds.
