This line works when run against Android, but fails against iOS with the error below. How can I identify the problem?

Using Debug View Hierarchy in XCode it looks like there are several layers on top of the textBox (_UITextLayoutCanvasView, UITextFieldLabel, and _UITouchPassthroughView). But they all look transparent

await element(by.id('FirstName')).typeText('John'); 

Error:

Test Failed: View is not hittable at its visible point. Error: View is not visible around point.
    - view point: {81.166664123535156, 28}
    - visible bounds: {{0, 0}, {162.33332824707031, 56}}
