Issue generating raster output from URock

[sstrumwasser]

I'm running into an error with URock when trying to produce a raster output. When I use no template for the output, everything runs fine. However I would like to use a template because we really need to speed up the processing however we can. The error I get when I use a template looks like this (in the QGIS Processing Log view):

2025-05-23T09:43:36     CRITICAL    Process returned error code 1

I have tried using a template that significantly exceeds the extent of the input and one that matches it perfectly (in fact, the DSM used in URock prepare to generate the buildings and veg polygons). Both cases produce this error. Any ideas about what's going on?

Thank you.

This might be an issue that have been fixed already. Try to download the latest development release of UMEP. We are about to release a new version to the QGIS repo but it is not yet ready.

I've installed the dev version but am now getting this error:
QgsProcessingException: Could not create layer [C:\Users\____\AppData\Local\Temp\order_changed.gpkg: Creation of data source failed (OGR error: A file system object called '[C:\Users\____\AppData\Local\Temp\order_changed.gpkg' already exists.)

Never got this error before but I have made a change in the last version. Can you try and report ? Maybe you will also get the same error for other files. The fix does not take long, let me know

I tried the dev version with my data and the tutorial data (Annedal_EPSG3006) and am getting this error:

Any idea how to fix it? It is happening during the "Rotates geometries from -45.0 degrees" step. I think it's line 550 in saveData.py.

[j3r3m1]

It should not happen any longer since order_changed now have a time dependance (https://github.com/UMEP-dev/UMEP-processing/blob/ae0c7a349537adcae774203879dae7d77709a3ad/functions/URock/saveData.py#L556).

Could you please uninstall all UMEP versions you have and install only the zip (last version should be 2.1.24)

[sstrumwasser]

I'm running the dev install on a different machine and getting the following error during rotate geometries in URock:

RuntimeError: [C:\Users\*****\AppData\Local\Temp\interp_before_fillna.tif](file:///C:/Users/******/AppData/Local/Temp/interp_before_fillna.tif): No such file or directory

Do you know the cause of it?

[sstrumwasser]

I uninstalled and installed the dev version from zip and it works fine. Thank you for your help!
