Simple query fails after long runtime, ends up being a type error?

[EMCP]

I am owner of a Trino server running V415 .. attempting to query it via Julialang.. and the HTTP api doesn't make much sense to me .. so I grabbed JDBC and attempted to query a simple select * from my_table .. but getting an error

here's the code

using JDBC
using Tables

driver_path = "/home/emcp/drivers/trino-jdbc-415.jar"

JDBC.usedriver(driver_path)
JDBC.init()

cnxn = JDBC.Connection("jdbc:trino://mytrino-server:8080/hive/my", props=Dict("user" => "hive")) # create connection
csr = cursor(cnxn) # create cursor from connection

# execute some SQL
execute!(csr, "SELECT * FROM my.table")

# Create a Vector of NamedTuples from the cursor rows
rows_data = NamedTuple.(collect(rows(csr)))

# Convert the rows vector to a Table.jl table
table = Tables(rows_data)

close(csr)

on the collect line it gives

ERROR: TypeError: in typeassert, expected Symbol, got a value of type Char

as others have remarked the performance was quite bad, but I understand the state of the project is that it's a last ditch sort of thing.. but thought it'd be worth posting this as it may be occurring for others when getting started
