Dart's Node wrapper code in `npm:sass` does string slicing on the thrown error message which broke because of our missing uv error context. Code in question: ```js _systemErrorToFileSystemException0(callback) { var error, t1, exception, t2; try { t1 = callback.call$0(); return t1; } catch (exception) { error = A.unwrapException(exception); if (!type$.JsSystemError._is(error)) throw exception; t1 = error; t2 = J.getInterceptor$x(t1); throw A.wrapException(new A.FileSystemException0(J.substring$2$s(t2.get$message(t1), (A.S(t2.get$code(t1)) + ": ").length, J.get$length$asx(t2.get$message(t1)) - (", " + A.S(t2.get$syscall(t1)) + " '" + A.S(t2.get$path(t1)) + "'").length), J.get$path$x(error))); } } ``` Fixes https://github.com/denoland/deno/issues/26994
