Research direction

Reproduce the failure with session.getColumns(...).fetchAll() and inspect JsonResult.js, especially getColumnValue, getSchemaValues, and getRows, along with DBSQLOperation/getResult.js. Done means fetching table columns no longer throws while decoding the result and returns the expected column data.

getting an error when I try to get columns of the table.

code that I am running:

query = await session.getColumns({
    catalogName: request.database,
    schemaName: request.schema,
    tableName: request.table,
});

const result = await query.fetchAll()
