Hi mkubik ，

Is your issue solved?

Hi mkubik

I have faced similar error while refreshing and solved now.

1. Maybe be because of gateway updation (reinstall the gateway) 

2. check the database, accidently you have deleted any tables or not which you have used or refered in your dashboard. (For me there was no error shown in the dashboard but while refershing in the app.powerbi am getting this error refering to that table 

Data source error{"error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","pbi.error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","parameters":{},"details" .............."exceptionCulprit":1}}} Table: The_table_name_that_i_have_deleted_from_db )

I have deleted that table from the dashboard and republished with the changes, now refresh works fine.

Also for me gateway was "online" means gateway is fine i guess (error was still there) thats why i checked my db.

app.powerbi > settings > manage connections and gateways > on premise data gateway > click on that icon > online/offline

Hope this helps.

Thank you 😊
