I can´t open projects from gateway on client computer.

Any idea what this error on the gateway is related to and how to fix it.

We are going to need to see the script to help.

That is the stack trace, can you provide the actual timer script referenced?

if I restart the gateway may fix it

Is that the entire script file?

Specifically lets start with this timer script:

```python
Copy_Of_Version-12_5-01-08-25/MAX_DNF_KW

```

Would it help if I use bacck-up of gateway before I got the error ?

I don't know. I have not seen the script.

We aren't magicians, and that error is pointing to a specific error in your script. If you can't provide the script that is causing issues so we can help you decipher what is going on, all you are doing it guessing at the issue and not fixing it.

EDIT  
What is the actual problem you are trying to solve? You started with an error in a timer script, and then you provided what seems to be script from a perspective view. They might be related, but what are you trying to fix?

Now i cant open projects on my Ignition client, so I guess just doing backup of the gateway will go to previous point so I could open at least older projects.

One way to get this error, is the following:

```python
path = "[your]tag/path"
config = system.tag.getConfiguration(path)
print config['name']

```

getConfiguration returns a list, so you must read the first item through config[0].

I however cannot verify this, because i can’t see what line 67 is in your code. Please share that piece of code, or start looking there.

This pretty much means nothing to an end user, it's just part of the stack trace. The important part of a stack trace are the lines that start with `Caused by:` In this case you have a timer script running which is called `Copy_Of_Version-12_5-01-08-25/MAX_DNF_KW`. In that timer script on line 6 you are calling a function comprobarGuardado. In that file on line 61 you are trying to access a list element with a string which can not be converted to an integer.

> [@Alejandro\_Alaco](#):
>
> the last piece of code I was running:

This code does not match the stack trace you provided. We know this because the stack trace calls out a Gateway Timer script, but the code you provided uses `self.getSibling()` which is not available in a Gateway Timer script.

The error you proivided in your OP also doesn't match the stack trace you provided. That error looks like you may be having network issues, in which case I would not expect a backup to correct the issue.

Yes, exact that, was a network issue, I just was able to open the project.

Thanks everyone for your answers @bschroeder@JVDM and @lrose

I didnt need to do any backups and can keep working fluently without any issues.
