Getting [] response from Swagger for certain GETs Assets/{id}/effectivemanagedby

I'm using the swagger API. I've logged in and authorized my session.

I have all of the required permissions (Authorizer, Auditor, Asset, Appliance, Security Policy, User, Help Desk, Operations, Application Auditor, System Auditor)

When i'm trying to run certain GETs, for instance GET/v4/assets{id}/EffectiveManagedBy

I know my AssetID  and all of the other parameters are set to default values. 


When I run the GET my only response in the body is []

response headers 

 cache-control: no-cache,no-store,must-revalidate  content-language: en-US  content-length: 2  content-security-policy: object-src 'none'; img-src 'self' data:; font-src 'self'; script-src 'self'  content-type: application/json; charset=utf-8  date: Wed,08 Apr 2026 15:25:02 GMT  referrer-policy: same-origin  strict-transport-security: max-age=63072000; includeSubDomains; preload  vary: Origin  x-cluster-role: primary  x-content-type-options: nosniff  x-frame-options: DENY  x-tokenlifetimeremaining: 1431  x-xss-protection: 1; mode=block 




I'm not sure what I'm doing wrong here. Any guidance would be greatly appreciated. Thank you
