module-descriptor-invalid: Invalid module descriptor

Cause

A descriptor in modules, or a value returned by importHook / loadHook, does not satisfy the module descriptor contract:

• The descriptor must be a non-null object containing exactly one of source, namespace, or specifier.
• source must be a string or a structurally complete ModuleSource.
• namespace must be a non-null, non-array object. Ordinary objects are accepted.
• A redirect's specifier must be a non-empty string.

Troubleshooting

1. Use the module specifier and field name in the message to locate the modules entry or hook result.
2. Check whether the descriptor combines multiple forms or the hook returns a source string directly.
3. For precompiled modules, check whether any ModuleSource fields were omitted or modified.

Solution

Return one of { source: code }, { namespace: exports }, or { specifier: target } according to the module source. Hooks should return a promise that resolves to the descriptor. Use the public precompileModuleSource API to generate a complete precompiled artifact and place it in source; do not manually assemble an object with missing fields.
