Describe the bug
I'm using the python code present in
https://docs.flowiseai.com/using-flowise/document-stores#id-10.-api
Want to reproduce:
Scenario 1: In the same document store, use an existing document loader configuration, upsert as new document loader.
But a after running the script a new document store is created

This is body data I've used

body_data = {
    "docId": DOC_LOADER_ID,
    "replaceExisting": False, 
    "createNewDocStore": False,
    "metadata": json.dumps({"docname":"coldfusion","line":"1"})
}

Expected behavior
As described in Scenario 1:
In the same document store, have a new document loader, with the configuration of the original/source.
