Coastal Vulnerability - TypeError: cannot unpack non-iterable NoneType object

[BatTerZ]

Hello!
I try to run model with my data, and got error.
need some help, please =)

I try to change inputs, output folder, model resolution. Error still the same.

Here where i am try to run model

HI @BatTerZ -

Please upload the entire log file (.txt) that the model produces in your Workspace. This includes information about the model version and the inputs that you provided that may help us figure out what’s happening. Thanks!

Hi @BatTerZ , thank you for uploading your logfile. This is a rare error that probably has something to do with the geometries in your Land.shp. Could you please share Land.shp and AOI.shp (and all of the associated files with different extensions - Land.* and AOI.*) so that we can try to reproduce this? You may share a link to google drive, dropbox, etc if the files are large.

Thank you,

[BatTerZ]

Hello! I try to reduse size of AOI and it works. Problem with start AOI still remain.

Hi @BatTerZ , thanks for sharing your data and for trying to troubleshoot this. The problem turned out to be a very unlikely case where the land polygon has two vertices that are very nearly in the same location. These are their coordinates in units of meters (after converting to the UTM projection of the AOI)

There is a bug in the model that failed to handle this case properly. We will fix that. For the time being, I ran Land.shp through a “simplify geometry” algorithm in QGIS, with a tolerance of 1cm, and that seems to have solved the problem. Here is that new shapefile.

Thanks for helping us find this bug,
