dbt-glue stripping off double quotes in the data

dbt-glue has the code sql.replace(‘"’, ‘’) which is stripping off double quotes within the data.
Any idea why it is there?
Detailed Excerpt pasted below:-

SQLPROXY = """
import json
import base64
class SqlWrapper2:
    i = 0
    dfs = {}
    @classmethod
    def execute(cls,sql,output=True):
        sql = sql.replace('"', '')
