Hi, Georg. Thank you for your comment.
Sorry, Let me explain the situation.
First, Studio Pro ver is 9.11.1.
The errors that occurred after pressing the run locally button and the view app button were shown below.
And microflow is below.
Do you need any other information? Any help would be appreciated.
Thank you for your comment.
The postgres driver is added to the userlib folder under the application. (Bottom of the image)
Am I putting the files in the wrong place?
Also, I thought the connection itself was working, since pgadmin4 seems to be getting the information in the mendix.
Just to double-check, have you added the Postgres driver to the connector?
You can find the details in section 2 of the documentation: https://docs.mendix.com/appstore/connectors/database-connector/
