im running into an issue trying to use

upsert_nodes

.............. *clipped for brevity* ..............

my insert statement looks like this

graph_store.upsert_nodes(nodes)

and my graph store looks like this

graph_store = NebulaPropertyGraphStore(space=space_name, props_schema=", ".join(props_schema))

i am manually adding my schema tags and edge types in a separate codeblock. That seems to not matter as when i look at the source, the issue appears to be coming from some forced default nebula syntax entry within llama_index Is it required that I copy the syntax used and manually add it to my schema? i'm confused on the correct way to work around this error
