OpenSearch Connector Issue

[Step1N]

Hi,

Recently we have moved from elasticsearch to opensearch connector. Since trino is supporting opensearch connector.
While query index which has list of text_type of data , its throws error :

Expected a string or numeric value for field 'field_name' of type VARCHAR [AB_EX1,AB_EX2, AB_EX3] [ArrayList]

Has anyone faced this issue.

Opensearch version - 1.0.0

Thanks
