{specifier_name:?} not found in imported namespace {namespac

Error message

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

What it means

Fires from import/namespace when a property access on an imported namespace object (e.g. ns.foo) references a name the source module does not export. The no_export helper builds the message with the specifier and namespace names; it is reached from direct member accesses and from destructuring object patterns.

Solutions

1. Correct the property name to one the source module exports
2. Add the export to the source module
3. Destructure only names that actually exist in the namespace
