Power BI Dataflows have been systematically failing in the last 24 hours "because there was a problem with one or more entities, or because dataflow capabilities were unavailable". No matter if the dataflow queries our on-premises server or or a simple Excel file on SharePoint, it just fails. They have been running for a few months with no problem, beside isolated and temporary failures to refresh.
It seems that all dataflows are “pending validation”. When I open an entity and attempt to save it, it can’t save the entity/dataflow after the validation step fails. Herebelow is the error message that does not tell me much about the issue.
We have got a few organisational reports connected to these dataflows and users need daily refreshes. What can I do about it?
