Hi everyone,
Im a beginner with designer and im trying to view the past alarms. Whenever i press the refresh button which is needed to view the alarms. I get this error. when i see if I'm not sure where to start.
any help would be very much appreciated
Best wishes
Looks like some script was converted from v7.9 and the script library names changed.
Show us the script (use the preformatted text option in this forum) so we can see the lines mentioned in that backtrace.
I'm defiantly being dumb and blind, where can i find this script?
The button you clicked has an actionPerformed event script, as noted in the error. In the designer, right click on the button and pick scripting from that context menu. (Or select the button and press Ctrl-J.)
Really Sorry for the late reply, So I went to the button, pressed control J and opened the script editor. From this it seems that there is only 2 lines of script? not 208 
Best wishes
So I might have found the line 208. However, I had to press the timer icon to find it. Not sure why though?.

The is one exceedingly dangerous background script. It is freely accessing components and their properties from a background thread. This can and eventually will completely lock up your designer or your Vision client.
It must be completely rewritten to not do that. See this topic for techniques to follow when using asynchronous tasks:
(It is an old post, but still applies to Vision.)
Read the whole thing.
Hi everyone,
I'm a beginner with this so any help would make me happy lol. I imported this project and im trying to view the alarms. However, Every time, I go to press the button. I get this error.
I checked if the key data exists in the dictionary and it doesn't. not sure what to do now.
Any help would be much appreciated.

I moved this post back into this topic. Duplicate posts are against this forum's rules. Please read the "Keep it tidy" section, @farhad_Hossain .
thanks for that. 
For the original issue with the global name shared, it was not in my global scripting. I think that what its called. So i imported the scripting from the original project and now I didn't get that error. However, something new pops up which mentions about a data key.
Your script console example shows you creating a dictionary with just an "error" key, then looking up a "data" key. So of course it doesn't have it.
As for your original code not have a "data" key in the given dictionary, there's no way to tell why. You will have to study all of the relevant code, and probably add logging of variables to see what is going on. Which you probably need to do anyways when you rewrite the asynchronous function.
Erm, could you just use the alarm status table or alarm journal component to show alarms?
I'm not sure ill give it a try.
Some background. This is an imported project, so the original one works fine, and im just doing it for testing small new changes.
