Trying to aggregate 1Sec data using ondickagg.so causes panic

[goodboy]

This may relate to #201, #108, #128.

Using the following mkts.yml config:

root_directory: data
listen_port: 5993
grpc_listen_port: 5995
log_level: info
queryable: true
stop_grace_period: 0
wal_rotate_interval: 5
stale_threshold: 5
enable_add: true
enable_remove: false

triggers:
  - module: ondiskagg.so
    on: "*/1Sec/TICK"
    config:
        # filter: "nasdaq"
        destinations:
            - 1Min
            - 5Min
            - 15Min
            - 1H
            - 1D

  - module: stream.so
    on: '*/*/*'

I get the following null deref from the server when trying to write */1Sec/TICK data using the standard client:

This would confirm that aggregating 1Sec data is not yet supported?
