The Resource Has reached Your Browser's Call Stack Limit


You receive a message in a resource in the Verbum web app that An error has occurred.

We and other web apps are leveraging WebAssembly making our web app more complex. Apple has begun to limit the complexity of code that can be run in a browser on iOS 13.

Our Resources require these advanced display technologies provided by WebAssembly to enable features such as notes, highlights, and visual filters along with other Verbum tools you have come to love in the Verbum desktop experience.

As a result, in some instances, resources may exceed the limitations enacted for browsers in iOS 13.



  • Turn off Notes and other visual filters, and retry
  • Use the Verbum web app in limited view by clicking "Turn on limited view"
  • Use the Verbum iOS app
