Postgresql and Power BI connection error: An error happened while reading data from the provider

I was connecting to the Postgresql database, after installing npsql, it got connected, and it asked me the server and database name.

I have given

Server: localhost:5432

Database: Test    - The database is already present in the Postgres. Then click OK. Then I am getting this below error: Details: "An error happened while reading data from the provider: 'Exception has been thrown by the target of an invocation.'

I have googled, but no luck, kindly guide how to proceed.

Hi @Sajeevsahadev,

 

Which npsql version did you installed? Please share the desktop trace log around the time that the error throws out.

Re: Postgresql and Power BI connection error: An error happened while reading data from the provider

Hi @Sajeevsahadev,

 

Which Power BI desktop version did you run? When I try the Power BI desktop October version with npgsql 3.2.5 provider, I can get data fine. Please update the desktop to the latest version as ours then test again. 

 

Best Regards,
Qiuyun Yu
