Length cannot be less than zero error on build

[mesuttavukcu]

Hi. I am using startsharp .net core version 3.12.0.6. I am getting this error on build. It builds the project and its working but typescript doesn't generate row properties, custom endpoint functions etc.
Error is:

System.ArgumentOutOfRangeException: Length cannot be less than zero. (Parameter 'length')

can someone help?

I don't know why but I solved it. First I copied a working net core project then i copied my modules into that project everything was fine until I copied a custom class file into that project. then it failed servertypings again. than i deleted that class and it worked again. now i re-created that class and its working. very strange but this solved the problem for me.
