Please help

Hi Vivek,

Sorry for the confusion. This isn’t actually an error, the message on the console is misleading in how actionable / relevant this is.

This message occurs anytime that formplayer doesn’t find an existing “Sandbox” to store the data for a user. It’s expected that will be the case in many circumstances, including, for instance, the first time that a user jumps into a formplayer app.

This will only indicate a problem if you are seeing the message every time a user performs a web apps action, which could indicate that the system is having problems reading from persistent storage.
