Problem description
The Id specified in the PutBucketInventory request already exists in the bucket's inventory configuration.
Causes
Each inventory in a bucket must have a unique Id. The Id in your request matches an existing inventory already configured for the same bucket.
Examples
A bucket can have multiple inventories. However, the Id of each inventory must be unique within the bucket. If you submit a PutBucketInventory request with an Id that is already used by another inventory in the same bucket, OSS returns this error.
Solutions
Change the Id value in your request to one that is not already used by any inventory in the bucket.
