Are you still facing this issue? Unfortunately, I am not able to access the GDB Dashboard 1/2. I am also guessing you are using the ArcGIS Online version of Insights for your dashboards. I saw your screenshots and
Are you doing any joins, locate or spatial operations?
Is it possible for you to share a sample dataset and reproducible steps? I understand you are uploading a zipped GDB but would like to know what else you are doing other than creating a Predefined filter and Timeseries chart.
Thanks for reaching out. It's a pretty old post and I don't remember the details. It could be possible that I did a join, but I don't recall it. The team decided to switch to R Shiny due to some other limitations. I don't work for this organization anymore, so I cannot backtrack what happen to the dashboards you cannot open anymore.
