makeWebRequest Error with VENU MB Collec. while working with VENU

Hi guys,

i tried to find some tips already exists in the forum about that but did not find any.

I'm working on a new WF, and now i'm testing it.

It (seems to) is working on any devics , even on VENU (390x390),except VENU Mercedes Benz Collection.

in the BG process, makeWebRequest is launched, and - only with VENU MB Collection, it returns :

Error: Symbol Not Found Error
Details: Failed invoking <symbol>
Stack:

here are some println on VENU MB:

Background: initialize WebRequest
initialize inital view APP
390
Background: initialize WebRequest
Background: **** WebRequest calling makeRequest id=**** 9xxxx
Background: **** makerequest**** ****
Background: {email=>xxx, L=>xx.448065, apikey=>xxx, G=>xx.861368, uuid=>xxx}
Background: **** makerequest**** Launched ****

Error: Symbol Not Found Error
Details: Failed invoking <symbol>
Stack:

I can see http data back in the http Traffic logs, 200 return code and well formed datas.

here are some println on VENU and others watches:

Background: initialize WebRequest
initialize inital view APP
390
Background: initialize WebRequest
Background: **** WebRequest calling makeRequest id=**** xx
Background: **** makerequest**** ****
Background: {email=>xx, L=>xx.492135, apikey=>xx, G=>xx.840163, uuid=>xx}
Background: **** makerequest**** Launched ****
Background: **** receiveResponse**** responseCode **** 200
Background: **** receiveResponse**** Will exit **** {xxxxx}
Back in onBackgroundData ----------- dataFromWebRequest = 200*** {xxxxx}
in onBackgroundData ----------- Saving : {xxxxx}

I checked memory usage, about 42k and peak at 53k.

So i have 2 questions :

- Is there any way to have more stack info on the error (i tried debug with no more info)

- What could be the difference between VENU and VENU MB ?

At this point, i deleted VENU MB Collection from my manifest...

Thanks for your help.
