Possible bug on code autocomplete pgadmin V 3.0

Hello everyone in the list. After installing pgadmin4 V 3.0 from source, the autocomplete code  on query tool is not working, these errors are logged in my apache-error.log. I think this is a bug. Is there any help to solve that?

PgAdmin4 was installed from source code and running behind apache2.4 server.

Regards
