I am using komapper and QueryDSL to import data from mysql, but if there is geo collection type data in the data, the following error occurs.

java.lang.UnsupportedOperationException: An operation is not implemented: not implemenetd for 255

I need to know if there is a way to handle the conversion or if this is an error.

The libraries use version 1.16.0 for komapper and 2.2.4 for jasync-sql

Please check this problem. 🙏
