Unresolved runtime dependencies

I have done a scan with this command "scancode --license --copyright --package --info" and it seems that it cannot resolve licenses for runtime dependencies found in npm package.json file.

Example:

"purl":"pkg:npm/bluebird"
"extracted_requirement":"^3.5.3"
"scope":"dependencies"
"is_runtime":true
"is_optional":false
"is_resolved":false
"resolved_package":{}0 items

Scancode v32.0.8 and python 3.11 on Windows

I would expect it to find an MIT license for this package...
