After update mysql2, LOAD LOCAL file asks to stream

See original GitHub issue

When using mysql2 1.6.5 with TypeORM and running the query bellow, everything goes as expected, but after upgrade to 2.02 version, I get this error.

// CODE
this.connection.query(`
LOAD DATA INFILE '/home/data.csv' INTO TABLE studio_data
  FIELDS TERMINATED BY ',';
`)

// ERROR
As a result of LOCAL INFILE command server wants to read /home/data.csv file, 
but as of v2.0 you must provide 
streamFactory option returning ReadStream.

Connection

const connection = createConnection({
                    name,
                    type: credentials.client,
                    host: credentials.host,
                    port: Number(credentials.port),
                    username: credentials.user,
                    password: credentials.password,
                    database: credentials.database,
                    logging: true,
                    dateStrings: true,
                    multipleStatements: true,
                    supportBigNumbers: true,
                    bigNumberStrings: false,
                    flags: ['+LOCAL_FILES'] // <======
                });

Query

return connection.query({
            sql: ` SET SESSION sql_mode = '';
                      LOAD DATA LOCAL INFILE "${localFileToImport}"
                      INTO TABLE ${taskData.resultTable}
                      ${characterSet}
                      ${fieldsTerminatedBy}
                      ${optionallyEnclosedBy}
                      ${linesTerminatedBy}
                      ${ignoreFistRow}
                     ${transform.columns}
                     ${transform.replace}`,
           values: [],
           infileStreamFactory: () => fs.createReadStream(localFileToImport)  // <======
        })
