What causes this issue?

You have used a '/' in the name of a semantic group. This character is
normally used for namespaces.
This character is not allowed here.
The semantic group is a kind of generator, which cannot be transported
itself, but which can be used to create DataStore objects (advanced) and
CompositeProviders. The generated objects can be transported.
Because of this special behavior, we do not allow namespaces (with '/')
in the names of semantic groups. However<(>,<)> you can use namespaces
for the objects, which are generated by the semantic group.
