The following typo was spotted by @msommer24 :

"In the doc at https://meteoswiss.github.io/dvas/running_recipes.html#execution-of-a-dvas-recipe, there is a ``uaii22.rcp`` instead of ``uaii2022.rcp``."

Open the linked running_recipes.html page and locate the execution-of-a-dvas-recipe section. Confirm the filename shown there and verify that the rendered documentation uses uaii2022.rcp rather than the reported uaii22.rcp.
