SAP Document Management Service (DMS) - CMIS CreateFolder 404 Error

[#1]

Hello SAP Community,

I'm trying to use SAP Document Management Service (DMS) to create a folder and upload files via API. My goal is to create a "Config" folder under the root folder and then create documents inside it.

Steps I've completed:

1. Created instance and service key in BTP
2. Created a repository
3. Obtained access token
4. Attempting to create a folder

My request:

• Endpoint: POST /browser/95d4b7c4-a5a9-4e60-a833-c0e70c7bc85a/root
• Parameters:
  • cmisaction: createFolder
  • propertyId[0]: cmis:name
  • propertyValue[0]: Config
  • propertyId[1]: cmis:objectTypeId
  • propertyValue[1]: cmis:folder

Error response (404):{
"exception": "objectNotFound",
"message": "I164G401lYkqZAwqysJowaWo4vuhRv7CeNEJp3IDI9I"
}

What I've verified:

• The repository exists — I've confirmed this using the CMIS Fetch Repository API　attached ”browser.txt"

Environment details:

• API: SAP Document Management Service, Integration Option - CMIS → Create Document
• Documentation: https://api.sap.com/api/CreateDocumentApi/overview
• Testing tool: Business Accelerator Hub "Try Out" feature

Question: This error suggests that the object cannot be found. However, based on the Fetch Repository API response, both the repository and root appear to exist.

      ●Are the API being used and the request contents correct?

　●Is there an additional step required before creating folders under root?

Please let me know if any additional information is required.
