Unknown Type ID error

I was following this post and I get the error below when I add 3 components as Boundaries, MoveSpeed, MoveWithInput.

Hi @etienne_unity My version is 2018.3.0f1. I downloaded it from the unity hub if that matters. I tried your workaround suggestion but still the same error.

 

Yes I was getting with a new project.

I tried those 3 steps again. It gave the same error after I create a custom Component. But then I deleted all other samples from the tiny samples folder and reimported all the project, and it worked. Thank you both

 

I had an error like that when I assigned a custom Component to an Entity, then deleted the Component and created it again with the same name. The Entity didn't update to use the new version of the Component automatically, instead pointing to the old deleted one -- but the error message didn't really point in the right direction, I just had to click around until I found the Entity with the big red alert in the inspector view.

No way to know now if this was the same reason you saw the unknown type id error but that's how I was getting it. Here's a screenshot of a Camera entity with both an old, deleted MyComponent reference AND a new, existing MyComponent added at the same time:

And the resulting error on startup (you can see the full error in the console too but only if "clear on play" is turned off -- and it doesn't lead you back to the offending Entity anyway):

 

@Berzee I see, I saw the same red error on inspector when I deleted the component but since I tried so many things, I can't remember the exact flow I took. So the reason could be about anything in my case
