comma in the process variable result

Question

im executing a process that is returning this i dont understand why there is a comma before the result of the map which is returning errors in other nodes how can i fix this?

Could it be that this is some sort of a list? That would mean that the problem is not that comma, but that NULL value as the first item in the list.

please edit this comment and re-copy-and-paste your code into a Code Box, because like this it's pretty much unreadable, thanks to how indentation and formatting are stripped out by Community. 
 Note: I see you've moved it into Code Boxes, but if you re-copy it from the Appian source, you'll actually get indentation instead of the hard-to-read "flat text" like what we see currently after your first revision (which is still very hard to read):

Can you share the expression code and/or configuration of the node that returns this? 
 To clarify, are you just asking about the part that has "modified ,{..."? The rest looks like typical CDT / dictionary data.

Ok, thanks for clarifying, now how about my first question? Without answers for that we have no way of guessing what might be going wrong.
