The value NIL is not of type PGLOADER.CATALOG:COLUMN

[teeravee]

Hi,

I try to load data of Metabase from MySQL to PostgreSQL using pgloader but always get the error message The value NIL is not of type PGLOADER.CATALOG:COLUMN.

• pgloader --version

pgloader version "3.6.7~devel"
compiled with SBCL 2.2.9.debian

• pgloader output you obtain
  The value NIL is not of type PGLOADER.CATALOG:COLUMN
