Any one experiencing this in production? I've undeploy everything but still got this issue ;(

Might need to be a bit more specific about when this happens.

this isnt a platform issue, its something in your accont 🙂 need more details

This happen for ALL transaction data, when I "VIEW" or "EDIT" or "SAVE".

Check your workflows

when did it start? what was the last thing you or someone on the admin team did that was a system wide change? revisit that change ... 🙂

custom script has unhandled exception. developer is needed to troubleshoot it. power user/admin won't be able to get it resolved. you can try disabling scripts on this record type one by one till the error goes away. then you found the script causing it. still someone needs to dig into the code to debug it.
