Getting 1346458189 ('PARM') error

[Guest]

From the readme:

"An Illustrator error occurred: 1346458189 ('PARM')" alert (1459349)    Affects: JavaScript    Problem:     This alert may be popped when badly written scripts are repeatedly      run in Illustrator from the ExtendScript Toolkit      Scripters need to be very careful about variable initialization and      namespace conflict when repeatedly pushing a batch of Illustrator scripts     for execution in Illustrator via the ExtendScript Toolkit (ESTK) in a      single Illustrator session. Each script run is executed within the same      persistent ExtendScript engine within Illustrator. The ESTK debugger      uses BridgeTalk to communicate with Illustrator. One global, persistent      ExtendScript engine inside Illustrator handles all BridgeTalk      communications. The net effect is that the state of the ExtendScript      engine is cumulative across all scripts that ran previously.      The following issues with script code can cause this problem:        - Reading uninitialized variables.        - Global namespace conflicts, like when two globals from different         scripts clobber each other.    Workaround:     Initialize variables before using them, and consider the scope of      your variables carefully. For example, isolate your variables by      wrapping them within systematically named functions. Instead of:             var myDoc = app.documents.add();       // Add code to process myDoc           Wrap myDoc in a function that follows a systematic naming scheme:             function myFeatureNameProcessDoc() {      var myDoc = app.documents.add();      // Add code to process myDoc      }      myFeatureNameProcessDoc();

This makes zero sense to me. If javascript variables are being reused or 'clobbered' or your javascript is 'poorly written' (this is not defined) it should have no effect on the scripting engine. Errors should cause exceptions to be thrown, which can be caught by the script.  I'm getting these errors when I try to evaluate properties of valid objects, for instance trying to access pathItem.fillColor. It's happening in various (almost random) lines in my script. Javascript doesn't have namespaces so I don't know what a 'namespace confilct' would be. Accessing variables from nested functions also seems to be a problem.

Edit - this seems to be related to accessing global variables or variables defined in containing functions. For now, adding var to the first use in subfunction seems to have fixed the problem. What is strange is you don't get an undefined variable error, it just crashes when it tries to access the properties.

Edit - still not fixed. I'm guessing it has something to do with memory allocation, because I am processing a lot of big raster images in todays batch of files.

Edit - processed 84 files today with no errors the pattern I'm using is to use a bach file that loops

"(Path)/Extend Script Toolkit.exe" -run script

sleep 10

The script opens a group of files (in my case JSON files), processes one file, exports an ai file, deletes the JSON file, then exits.

Also, run the script file out of the Adobe Scripts folder so you don't get the security prompt.

I was troubled by this bug for a long time as well.

But I have now found a very simple way, for now at least, that seems to perfectly resolve the issue:

Simply press the TAB key before running your script!

What that does is to remove all panels from the illustrator UI. And I believe the bug is related to illustrator wanting to create thumbnails in the layers panel (or other visual effects) when every doc is opened, and when you're batch processing files and modify their layer contents, illustrator can't keep up and gives you the PARM error.

I have a huge processing script that amongst other things moves every layers artwork into new artboards. I have to unlock and make the objects visible as well. Anyhow, my script rendered random PARM errors. I tried so many things; breaking up the code into small functions, pausing between documents, and many other things. Nothing worked. But the TAB-key has worked flawlessly for batch processing all my files for about ten times now.

Please note, this solution only worked when running the script from within illustrator. So place the script in this folder:

C:\Program Files (x86)\Adobe\Adobe Illustrator CS4\Presets\en_GB\Scripts

(adjust the path according to your language)

And then run the script from illustrator's the File->scripts menu.

I will have to take a look at this as I get an 'PARM' error and crash when ever I've tried to deal with Pattern Fill objects. Won't draw the screen then fold… no matter how simple the pattern.

UERIKA! I found a semi-solution. This error only occurs for me when my illustrator window is "maximised" before I close it. Try to make it so its not maximize before your script opens up Illustrator. 😃 hope this helps.

Hello

Just for anyone who will google for the same problem

In my case (also was a huge batch processing with javascript)  I've found the solution by inserting a delay between each iteration:

$.sleep(3000);

Maybe even less ms delay will work.

Thank you azgolfer for the direction!
