Hi @yordansoares,

I think I am having the same issue, as it arised after upgrading to version 3.6.3. When generating an invoice I get the following error (some data has been anonymized):

Fatal error: Call to a member function custom_field() on null

I am not a programmer and I can’t determine if your solution also applies in this case.

Many thanks in advance.
