This assertion is meant to prevent you from passing interaction matrices of incompatible shapes into fit and predict. In this case, I think your test matrix has a larger first dimension than your train matrix, and so there are some users in the test set that were not in the original train set.
Can you check that this is not the case?

Arguably the library should be more informative about what's wrong. I'll look into providing a better error message.
