Throwing errors when app is saved to and accessed from iOS Home screen
Opened this issue · 3 comments
I am using google-signin
in my app to check for credentials of the user, then allow/deny access to the main content. I am testing my app in several instances, and I saved my app to my iOS home screen using Safari.
When I am testing on desktop/mobile browser and hit the signin element, the browser opens a Google dialogue, which either auto-logs in or allows users to manually sign in, then closes and my app handles the outcome of that interaction.
After opening my app from my iPhone 6's Home Screen, I press the button to sign in and I am taken to a blank page; debugging returns the following issues:
Before pressing sign in button:
TypeError: null is not an object (evaluating 'this.$.getItem')
When I actually attempt to sign in, I get a blank screen and the following error message:
TypeError: null is not an object (evaluating 'this.c.setItem')
From what I can tell, the issue is with the google-signin
element's use of sessionStorage
which may or may not be supported by the browsing type; another potential issue is the sign-in dialogue not returning focus back to the app. (this may be due to the JS storage error)
It looks like an issue with google auth2 library. google-signin element does not directly use sessionStorage.
If you'd like to pursue this bug, you should file a bug with a reproducible case to the google auth2 library team.

@AlexanderSeto Is this for iOS as well? On Safari? I'm about to open an issue on the gAPI javascript page and want to be accurate.
