Error when flattening the source-map

[valentinstn]

Hi there,

I'm using ngx-tribute 1.5.1 within an Angular 11 project, but after yarn install I'm seeing a pretty weird error message and I don't know where it comes from.

...
Compiling ngx-tribute : fesm5 as esm5

Compiling ngx-tribute : esm5 as esm5
Compiling ngx-tribute : main as umd

I don't see any issue in the running application whatsoever. Does anyone have an idea how this can be fixed?

Thanks for the support!
