Erro de Visualização Power Querry

[MiguelAlenc]

Good Morning
I'm using powerbi using postgreeSQL as a data source, connecting via ODBX
When I load the tables and enter powerQuery for editing, some appear the following message "Preview.Error: The current preview value type is too complex to display.
Details:" What could I be doing to fix it?

Hi @MiguelAlenc ,

Please check if the prerequisites of connecting to PostgreSQL has been met, and install the latest Version of ODBC.

In addition,  you can refer the following links to connect to PostgreSQL in Power BI Desktop.

I've solved the problem installing Npgsql 4.0.10 WITH GAC(!!!)

When installing, make sure that you select NpgSQL GAC Installation.

This GAC did the trick.

Then reboot the machine.
