`NPE` in `Table.java` line 609 due to `null` `data`

[tatu-at-datastax]

I get NPE with stack trace of:

java.lang.NullPointerException: Cannot invoke "com.datastax.astra.client.collections.definition.documents.Document.map(java.lang.Class)" because the return value of "com.datastax.astra.internal.api.DataAPIData.getDocument()" is null
	at com.datastax.astra.client.tables.Table.findOne(Table.java:609)

for findOne command on (I think) empty table, no filters.
