hello everyone…
I faced this error 5to6 hours ago & I read all posts in Kodular community.
but my app error was not solved. but I find my app error easily.
THIS TRICK - COPY/DELETE/LAST/BUILD
For example - copy your project & open it, you can delete the last added components or blocks & build the app now.
if the app build is successful then you open the original app and check what mistakes you make there.
els the app build fails then you repeat the trick.

in my app, I added last time some components Lebals, Text box, Spiner & some Blocks.
I copied my project & opened it, and now I deleted the last added blocks & built the app.
it’s built successfully, then I back to my app and checked blocks.
i notice it in Spiner blocks " Elements From String " here missing only space.
For example - item1, item2, item3 but my item1,item2,item3

I hope this post is helpful for everybody…
Thank u for reading this post :wink: :smiling_face_with_three_hearts:
