SAGA Catchment Area fails in 3.10, works in 3.8

[mudomau]

Describe the bug
SAGA Catchment area fails to produce an output in QGIS 3.10, but the same algo with the same DEM works OK in 3.8

How to Reproduce

1. Load DEM
2. Run "Catchment area" algo from the default SAGA Processing toolkit (any method).

QGIS and OS versions
QGIS 3.10 running in Windows 10. Program language is english.

Additional context
Both in 3.8 and 3.10 the algo log shows an error message, but in 3.8 it produces an output while in 3.10 it doesnt.

@mudomau remind me of this #29346 not sure if it is the same.

@mudomau I just tested and here the problem is exactly #29346 .If in your case the output is not created can you please attach the DEM does not work for you?

[mudomau]

@gioman: Output is not created in 3.10 (on Windows 10) with the DEM attached. I tried the same in 3.8 and it was created (CatchmentArea output also attached).

Same for me on 3.10 (windows 10), the results from Catchment area are not being created.. Does it seem that this issue will be fixed or should I simply downgrade to 10.8 ?

Hello Mr. Gioman, I have the same error, and layer will not appear.

Has there been any fix? My QGis version is 3.4.4 madeira, and the SAGA version is 2.3.2.

I'm attaching the DEM.
Uploading dem.zip…

I'm attaching the DEM.

@oteito you haven't actually attached any data. Can you try again?

PS QGIS 3.4 is unsupported, you must try on 3.16 or 3.18.
