Not Able to Create or Publish Asset in Production Environments Through Postman Post Request Using HTTP Assets API

Hello,

I've been trying to use the HTTP Assets API to upload files, create folders, and publish assets in our AEM Production environment through Postman. While I'm able to successfully accomplish these tasks in our lower environments (local, dev, stage) I'm always blocked doing so in Production.

For example, when trying to create a new folder in production using this endpoint: "https://prod-example-url/api/assets/northerntrust/test/newTest"

With this in the body: { "class":"assetFolder", "properties":{ "title":"Test Folder9" } }

I get a 500 error: Unable to create node at /content/dam/northerntrust/test/newTest

Similarly, I've gotten errors when trying to replicate content that state: Warn: No rights to replicate. Request for de/activation got issued for/content/dam/northerntrust/test/test.doc

I have verified that the authorization is provided and that the user making the request has the proper permissions. I have also attempted to include a CSRF token. Other posts have suggested checking the CSRF filters in "/system/console/configMgr". I did this on local where I have access and POST request is added in the filters and the POST requests there are still successful so I do not believe this is the problem. 

Does anyone have any idea what configuration settings (or other issues) in production could be resulting in the failed POST requests?  

Greatly appreciate any insight!
