Developer Update August 2025

We are using a self hosted instance of AccountRight SE.

Since upgrading to version 2025.7 from 2025.6 the API interface is throwing a 500 Internal Server Error on invoice creation, which sounds like the same issue Martic has reported.

End point: POST /AccountRight/[retracted]/Sale/Invoice/Service/ 

API Error Log:
