Bug Asset is not a valid Asset or Scene error when building addreessables after adding string table

Hi.

I am using Unity 2020.3.15f2, Localization 1.0.5, and Addressables 1.19.19

I had issues with my addressables not building in an old project (8 months old) even though I am absolutely sure it worked before.

So I tried to fix it but no matter what I do I get the same error:

Code (CSharp):

1. Asset 'MyAssetPath' is not a valid Asset or Scene.

I get this for all my localization assets.

I even deleted all Addressables groups and created a new String Localization table, which automatically populates the Addressable groups. And still I get the same error.

Doing "Analyze" gives the same error

Code (CSharp):

1. ArgumentException: Asset 'MyAssetPath' is not a valid Asset or Scene.

So I'm not really what to do now.

EDIT: After further testing it would seem that the issue had to do with the length of the path or the asset name. I was using a very verbose asset name for my table and it was deep in sub folders.
It would have really helped having a more explicit error message explaining why the asset was not valid.
