Under the WSConfig section the call to create a connection says await WsSql.open(conf). That is wrong.
It should be
await WsSql.sqlConnect(confg)

This is the interface description. sqlConnect is exposed in index. ts for user convenience, and it is not a method of WsSql.

The issue is that the relationship between open and sqlConnect has not been made clear in the documentation. We will keep this open until the documentation is updated accordingly.
