Recently, an existing paginated report has not been able to run on our Power BI service/login. This was only detected this week, commencing 2 August 2021 - prior to this, we've not experienced this issue and have made no changes to the report. The report runs locally on my own computer (through Report Builder) without an issue. Additional testing and research shows that having the parameters in the report set to either "Internal" or "Hidden" is the cause of this - by switching to "Visible" and re-uploading to the Power BI portal, the report then loads without any error. However, we need the parameters to not be visible to the end-users - please can this issue be looked into as it appears to only be happening on the portal/PBI service.
