@PeterPetrik (with online-cog stuff)

It does not always crash on my device, but it always generates this error Log:

I tested it within cog branch

[PeterPetrik]

possible fix https://github.com/lutraconsulting/input-sdk/pull/66/commits/2f72626496a6d7311a49c36612549e510abf5837

How to make it crash with cog branch (https://github.com/lutraconsulting/input/pull/1957):

• download and open the project (it does not crash on my device, but generates the mentioned error)
• close app
• run app
• now it crashes (when the project should be opened as default one)

Also from that point on, I am not able to open the project. I can open other projects though.

[PeterPetrik]

This crash could also be related to proj datum grid not present, so it needs some proper debugging, and it could not be related to WFS maybe at all.

I use WFS layers in a project and it crash every time I open the project on my IPhone 13
