Data source error{"error":{"code":"DM_GWPipeline_Gateway_MashupDataAccessError","pbi.error":

Hi, 

I am getting the following error when refreshing a data set that has previously been running for months without any problems. 

I know nothing has been changed as I am the only person within our company who administrates our Power BI account and I am on maternity leave! I have other datasets linked to the same source data and tables which are all running fine without any issues. 

Does any one know how I can fix this? 

Thanks
