I created a a .pkg installer from my node-js project which I later signed using productsign tool. Then during the notarization step I got the following error: { "logFormatVersion": 1, "jobId": "...", "status": "Invalid", "statusSummary": "Archive contains critical validation errors", "statusCode": 4000, "archiveFilename": "....pkg", "uploadDate": "...", "sha256": "...", "ticketContents": null, "issues": [ { "severity": "error", "code": null, "path": ".../keytar.node", "message": "The binary is not signed.", "docUrl": null, "architecture": "x86_64" }, { "severity": "error", "code": null, "path": ".../keytar.node", "message": "The signature does not include a secure timestamp.", "docUrl": null, "architecture": "x86_64" } ] } Is there any way I can solve this problem? Should I first sign this library using my "Developer ID Application" certificate?
