Thanks Caiyun.
I’ve managed to reproduce the issue with the pbix file attached (https://www.dropbox.com/sh/86qwp644loqtz26/AADY88bz6Mn_Q_UgSa3lSAHEa?dl=0) published to a workspace (using a simple xlsx file, also attached in case). I’ve also attached a video of the issue. We’ve found the issue occurs irrespective of the data source or storage mode (i.e. sql server connection, published datasets, csv/xlsx via import etc). Note that the error does NOT present in the pbix file – only when accessing the workspace report.
I have a pro licence and the workspaces we publish to are in a Premium capacity – not sure if that will make a difference. We are on the February version of Power BI Desktop.
Power BI Online service version details are below. I can’t find any documentation regarding the Service version numbers so can’t tell if we have the latest version or not.
