Why do I get this error when refreshing Dataflows?

[HUAM]

I made a dataflows (PostgreSQL Database)

'get data' 34 tables, but there was a error when refreshing..

Error message is:

Hi @HUAM ,

I can't be sure as no one here really reads 'error log', but my first guess would be an issue with your Gateway.

First things I'd check:

- Enterprise Gateway is running and functioning correctly when refreshing other sources (network, on-prem SQL etc.)

- PBI Desktop file is using the correct data connector

- Power BI Desktop is updated beyond December 2019 release (NpgSQL 4.0.10 shipped with PBID from this release onward)

- Enterprise Gateway is not installed with a Postgre connector beyond NpgSQL 4.0.10 (NpgSQL 4.1 and later versions aren't compatible with .NET)
