SUEWS database prepare

[Seamona]

Hi, when I launch the DB Prepare I get an error. This is the traceback:
TypeError: '
Traceback (most recent call last):
File "C:\Users/simon/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\UMEP\UMEP.py", line 652, in SUEWSPDatabasePrepare

Do you have any idea how I could fix this?
Thank you

I cannot replicate your error and I am having a very similar setup and version. Did you make any changes in the database using the SUEWS Database Manager before you launched DB Prepare?

[Seamona]

yes I did to set my case study in a Mediterranean context, but I to try to solve the issue, I installed the plugin again, and now the changes are no longer listed in the database manager

So then there might be a bug in the Database manager rather than in the DB Prepare. Could you please specify how how you did your changes in the database and also attach your database.xlsx file. You find it in your_plugin_folder/UMEP/SUEWS_Database_manager/data

I used the "base" as reference for anything new I added, otherwise it would not validate the new element and i simply added the values and the names in the boxes.
These are the files I have in the folder indicated:
database.xlsx
database_orig_keep.xlsx
databaseCopy.xlsx
Thank you for your help
