The error message suggests that either the component name or SHA256 is incorrect. To confirm, try running the exportDetails API call without specifying the component name, (as an example):
curl -XPOST -H "Content-Type: application/json" <artifactory-url>/xray/api/v1/component/exportDetails -d '{"license": true, "security": true, "exclude_unknown": true, "sha_256":"5cbde1b4c6cb34db1771c93929d49a293b8ad5017f9bd76ed127d2fc7b7d8a1d", "package_type": "maven", "output_format": "json" }' -o components.zip If successful, it implies that the provided component name is the issue, if giving the only SHA256 and still the issue persists, it means that the file doesn’t exist in the database.
