{specifier_name:?} not found in deeply imported namespace {n

Error message

{specifier_name:?} not found in deeply imported namespace {namespace_name:?}.

What it means

Fires from import/namespace (with deep checking) when a property is accessed through a chained/intermediate namespace re-export (e.g. ns.inner.foo) and the name is absent from that inner namespace's exports. Emitted by no_export_in_deeply_imported_namespace during deep namespace traversal of nodes and object patterns.

Solutions

1. Fix the name accessed on the nested namespace
2. Add the missing export to the intermediate module
3. Import the symbol directly from the module that defines it
