Error: undefinied is not an object (evaluating 'iter[Symbol.iterator])

Hello,

Since then I get the following error message while runnig the app: Undefined is not an object (evaluating 'iter[Symbol.iterator ]). Can someone here help me with it as I have literally spend hours but unfortunately without any solution so far.

Thanks in advance.
