OpenCloud Assets API - POST on /assets, operation is not done after hours

I have a large .fbx file (~20mb) in size. I am uploading it using OpenCloud Assets API using POST on /assets:

curl --location --request POST 'https://apis.roblox.com/assets/v1/assets' \
--header 'x-api-key: {apiKey}' \
--form 'request="{ 
  \"assetType\": \"Model\",  
  \"displayName\": \"Name\", 
  \"description\": \"This is a description\", 
  \"creationContext\": { 
    \"creator\": { 
      \"userId\": \"${userId}\" 
    } 
  } 
}"' \
--form 'fileContent=@"/filepath/model.fbx";type=model/fbx'

Although the operation is successful, I get back an operation id and done attribute is false:
{"path":"operations/075d0e3a-7c8a-4b3d-bb24-9e54d6c61554","operationId":"075d0e3a-7c8a-4b3d-bb24-9e54d6c61554","done":false}

Querying the operation id on GET /v1/assets returns the same, done has been false for hours now. The asset is not in my inventory.

Is there a problem?
