Extract failed

Error message

Extract failed

What it means

Sentinel error from getFilesFromPostmanExportedDataDump: the importer runtime threw while extracting the JSON files from a Postman data-dump archive (invalid zip, missing entries, unreadable content). The original exception is swallowed and replaced by this generic 'Extract failed' message.

Solutions

1. Re-download/re-export the Postman data dump
2. Confirm the file is a Postman 'Data Dump' archive and not a collection JSON
3. Check the file is a valid zip
