Migrate tables with LOBs from RDS MySQL to OpenSearch using DMS

Question

I'm trying to migrate data from **RDS for MySQL** to **OpenSearch** using **DMS**, but since DMS can't migrate **LOBs** to OpenSearch, fields with **longtext **data type **are missed** from the OpenSearch.

I tried to use **DMS transformation rules** to transform longtext to **string** data type, but it didn't work!

What is the best solution to migrate all fields to OpenSearch without missed columns??
