Dear Support,

I am facing this error today everytime when I invoke the create_service of one of my collection. Please see the screenshot. I have tried to delete and re-import the service , but it doesn't work.
Before it was working. And yesterday I have changed the collection to a secured collection. I tried to change the collection back to unsecured , but still this problem persists. Please take a look at the screenshot and let me know if you want to take a look at my app.
Thanks

Hello,

Please open your code from 417th line. It looks like you add mapping from (to) array, which is undefined.

Hi Sergiy,

Good news and bad news. Good news is that I found out that one of the mapping fields caused the issue.
bad news is I can not understand why it's causing the issue. It is a Menu component mapped to a number field.
I have 4 fields like this on my page, but only this one causes the problem.
The field value is automatically set to "null", when invoking the service, strange!!
I want to set up a break point and debug it in google chrome, could you let me know how I can set up the break point in the line, in google chrome?
When I open the developer tool in google chrome, I just can not find the line.

Hi -

Please take a look at screen shot here, click on parts shown: http://prntscr.com/7lp9ul

Hi Illya,
I see that the file named "VM215451" seems to have all the event handler code belonging to my AddNewTask Page. I was able to debug my code and I found out the root cause.

So what is this VM215451 file? It looks like a name with ramdon number, and I can not file the file under "Source" tab of the developer tool.
Apparently this file is very important.Could you provide more information on it?
Thanks.

Dongzhi, you can use debugger statement in your own code: https://developer.mozilla.org/en-US/d...
