Can not be uglify

It's working without UglifyJS2. But after uglify, I got an error Error: not an error at selet query line . Is sql.js can't be compressed?

Origin Code

let db = new SQLjs.Database()
try {
  db.run("CREATE TABLE products_2 (product_id int, name char, origin_price int);")
  console.log('getRowsModified()', db.getRowsModified())
  db.each("SELECT * FROM products_2", [], (row) => {
    console.log('tables', row)
  })
}catch(err) {
  console.log('err', err)
}

after compressed

var t=new a.default.Database;try{t.run("CREATE TABLE products_2 (product_id int, name char, origin_price int);"),console.log("getRowsModified()",t.getRowsModified()),t.each("SELECT * FROM products_2",[],function(e){console.log("tables",e)})}catch(e){console.log("err",e)}

Start by reproducing the uncompressed and UglifyJS2-compressed snippets using SQLjs.Database, then compare the failure at the SELECT query and the reported “Error: not an error” message. Done means the compressed example runs the SELECT without error and the behavior is documented or covered by an appropriate regression check.
