Illegal access error in workflow

[oliver_shields]

Ive written the below code in an 'Approval - User' activity on a workflow. Its purpose is to pull users from a glide list field on the software table (the field itself is on the cmdb_ci table) and add them as approvers on a REQ task. However im getting this error: Illegal access to getter method getMessage in class org.mozilla.javascript.RhinoException

Please dont mock my code too much, im not a coder and most of my codes are frankensteins monsters from other bits of code people have written:

var r = new GlideRecord('sc_req_item');
r.addQuery('request',current.sys_id);
r.query();
if(r.next())
{	
var Approvers = (r.Variables.please_select_the_software_you_would_like.u_sw_add_approvers) ;
}
{
answer.push = Approvers;
}

Thanks for any assistance.

Not sure if you're still experiencing this issue, but I stumbled across your post while investigating my own issues and noticed a few things:

1. You haven't defined what "answer" is. You need to add "var answer = [];" in somewhere  before you perform the push. 
2. You're defining "Approvers", but calling it out of scope. Might work, but not good practice. Approvers might not actually be needed.
3. If you're expecting some results from the GlideRecord, you'll want to process everything in a while loop, including the push.

Try this (not tested)

var answer = [];

var r = new GlideRecord('sc_req_item');
r.addQuery('request',current.sys_id);
r.query();
while(r.next())
{
answer.push(r.variables.please_select_the_software_you_would_like.u_sw_add_approvers.sys_id.toString()) ;
}

I think you may have some items flipped around.  A couple of questions:

1) What table is this workflow running on?  is it a workflow tied to a catalog item?

2) If you are running it on the sc_request table and not sc_req_item what behavior do you expect when there are multiple items tied to a request?

3) Is the please_select_the_software_you_would_like variable a reference variable?  If not, what kind of variable is it?

4) Is the u_sw_add_approvers field a field you added to your catalog item table? If it is, is it also a reference field? 

A bit of sample code that will tell your Approval-User step in your workflow to use a value that is pulled from a variable when you run the workflow on a catalog item:

answer = [];
answer.push(current.variables.approver);

In this case, there is a reference variable on the catalog item called approver. Yours may look more like 

answer = [];
answer.push(current.variables.please_select_the_software_you_would_like.u_sw_add_approvers);

Hi Olivier,
By the time you queried to the RITM record, The RITM might not be ready. add a timer activity before it and try it.
if you are doing this inside approver activity, you can write as follows,
answer = [];
answer.push(current.variables.please_select_the_software_you_would_like.u_sw_add_approvers.toString());

Mark ✅ Correct if this solves your issue and also mark ???? Helpful if you find my response worthy based on the impact.
Thanks,
