PowerBI refresh fail - Expression Error.

[elliotstan]

Hi,
I am unable to refresh my powerbi data online since the last update. Have checked and made sure my personal gateway is up and working. Other Datasets working ok as well.

Have one dataset that is reporting an error

Data Source Error: [Expression Error] The name 'Table.TransformColumnNames' wasn't recognized. Make sure it's spelled correctly.

Any idea what could be causing this error?
Cheers in advance for any help.

I'm having the same issue with Gateway - the error is coming from a missing field that has never, ever been in a table.
