Why is there no download file when my target language is ready in the Interpretation API?

Dubbing and file export are separate steps. Create an export in the required format for the completed targetId and keep the exportId. Query the download using that exportId: for PROCESSING or RETRY, keep checking the same export; for READY, download from the returned url. This endpoint returns a state and address, not the media bytes. If the address expires, query the same export again instead of regenerating the dub.
