Question:
When I open a MapThat Project I get an error message stating – sequence contains no elements – what is causing this?
Answer:
This issue can be resolved by ensuring that for the chosen project you have at least one layer associated to it. Using the MapThat Admin forms, simply tick to reveal a Layer in a specific Tree and also ensure that the Layer is visible by at least One Role.
The Project will now open successfully.
