Hello there !

I started diving into Elastic stack world recently, everything was going well but when I wanted to take data from a new SQL server table via Logstash, I got this error :

 ![err](https://us1.discourse-cdn.com/elastic/original/3X/9/6/9690b411d96136e5d8b2573fd359787d32055e4e.png)

My config file looks like this :

 ![conf](https://us1.discourse-cdn.com/elastic/original/3X/4/c/4cc38a1538edc3317423ad859a049492e0aef827.png)

If anyone can help, I'd appreciate it ! Thank you 😀😀

It is having a problem parsing the last run metadata. That is stored by default in

```
"#{ENV['HOME']}/.logstash_jdbc_last_run"

```

I suggest you remove that file.

I created a new file and added the path to the config file, it worked ! 😄
