Without the apoc iterate procedure it works fine, which is really weird.

It's not about converting or not. It's whether you find the spot, whether it presses that button in you, he added. Rahman further said his faith has kept him on the right track and saved him from many falls.", "A consortium of lenders led by Bank of Maharashtra has taken 'symbolic possession' of Pune's Maharashtra Cricket Association Stadium over non-payment of loan by stadium authorities.

The channel had earlier apologised for the error. The Pakistan leader was in China to secure an economic package amid the debt crisis in the country."] AS text
CREATE (n:Node {text:text})
And then run the classification procedure:
CALL apoc.periodic.iterate("
MATCH (node:Node) RETURN node",
"
CALL apoc.nlp.gcp.classify.graph(node, {
// we retrieve gcp api key from static value storage
key: 'key',
// node property that contains the text
nodeProperty: 'text',
write:true
}) YIELD graph RETURN distinct 'done'", {batchSize:5})
This returns a weird error:
{
"Node[10728] is deleted and cannot be used to create a relationship": 1,
"Node[10729] is deleted and cannot be used to create a relationship": 1
}
The graph is static, so I am not importing or deleting any data. That makes it weird why some nodes do not exist.
If I try to match the nodes in the error
MATCH (n) WHERE id(n) IN [10728, 10729]
RETURN n
I get no results. However as soon as I remove the apoc.periodic.iterate it starts to work:
MATCH (node:Node)
CALL apoc.nlp.gcp.classify.graph(node, {
// we retrieve gcp api key from static value storage
key: 'key',
// node property that contains the text
nodeProperty: 'text',
write:true
}) YIELD graph RETURN distinct 'done'

I have run into a weird bug that was noticed before on community site: https://community.neo4j.com/t5/neo4j-graph-platform/use-of-apoc-periodic-iterate-with-apoc-nlp-gcp-classify-graph/m-p/56776
