URL: https://github.com/apache/arrow-adbc/issues/713
Hi, I was trying to play around with the Python ADBC driver for FlightSQL to
see if I could connect to a service we're building. Our service requires some
custom headers, but when I try to set them it breaks.
Example code:
```
from adbc_driver_flightsql.dbapi import connect
def main():
conn = connect(
"grpc://localhost:9876",
conn_kwargs={
"adbc.flight.sql.rpc.call_header.customheader": "1",
},
)
cur = conn.cursor()
cur.execute("select * from table")
print(cur.fetch_arrow_table())
main()
```
error:
```
panic: interface conversion: interface is nil, not adbc.PostInitOptions
goroutine 17 [running, locked to thread]:
main.FlightSQLConnectionSetOption(0x1004537f8, 0x0?, 0x100453701?,
0x14000002680?)
/Users/runner/work/arrow-adbc/arrow-adbc/adbc/go/adbc/pkg/flightsql/driver.go:249
+0x70
```
I don't have much experience with go, much less with Python bindings on top
of go, so I don't know how to even start debugging this. Any help would be
greatly appreciated!
