Web: Version and onUpgradeNeeded must be specified together

[vixez]

Steps to Reproduce
Use boxExists on web.

It seems like boxExists is not working properly on web.
i'm getting the following error:

Error: Invalid argument(s): version and onUpgradeNeeded must be specified together
    Non-error `null` thrown by JS does not have stack trace.
