We recently started working with the new Personal Data Management Gateway for Power BI. Overall, we really like it but the error messages in most of Power BI have left much to be desired.
One error that we were encountering made us feel like the service was flaky as it seemed to happen randomly. When we tried to refresh a dataset, we got this error:
The Power BI team came to the rescue and worked out what was happening. Turns out that you cannot currently refresh more than once every 5 minutes. That also includes within 5 minutes of your initial upload. Unfortunately, this is the error returned when you attempt it.
Apparently this 5 minute limit is going to be removed soon and hopefully that will be one less error we might see.
