Hi,
I think your Error lies in the Page Properties. You can easily define multiple Page Parameters (as you can see in the screenshots). But if you delete lets say a dataview on the page (where the datasource “context” was selected) The parameter stays in the page properties. Please check this view if the parameters are correct or delete all unused or unavailable items:
Here you can see how i managed to add multiple page parameters:
This would be your Dashboard page with multiple Entities:
And this is one way how to call the page (can be done in a Microflow, nanoflow, etc. aswell :
So if you have any error like this:
Please check the page properties if there are any old parameters that are expected still listed in there
