I’m trying to run an HRA model with some random number I put into the CSV files, but I keep receiving this error: The following stressor-habitat pair(s) do not have at least one exposure rating: [(‘RCF’, ‘Roads’), (‘RCF’, ‘MIN’), (‘RCF’, ‘OPL’), (‘RCF’, ‘SET’), (‘RCF’, ‘DCL’), (‘RCF’, ‘BRL’), (‘UDM’, ‘Roads’), (‘UDM’, ‘MIN’), (‘UDM’, ‘OPL’), (‘UDM’, ‘SET’), (‘UDM’, ‘DCL’), (‘UDM’, ‘BRL’), (‘DIM’, ‘Roads’), (‘DIM’, ‘MIN’), (‘DIM’, ‘OPL’), (‘DIM’, ‘SET’), (‘DIM’, ‘DCL’), (‘DIM’, ‘BRL’), (‘WAB’, ‘Roads’), (‘WAB’, ‘MIN’), (‘WAB’, ‘OPL’), (‘WAB’, ‘SET’), (‘WAB’, ‘DCL’), (‘WAB’, ‘BRL’)] Here’s my data. Can anyone tell me what is wrong with it because I can’t seem to find anything?

Hi @kurapika , thanks for posting. I happened to be debugging something else in this model the last couple days, so I will take a look at this problem as well. It could help to have your “Habitat Stressor Information” CSV. Could you upload that also please? Thanks, ---

Hi Dave, Thanks for your help. Here’s my Habitat Stressor Info too as requested. [Habitat and stressor information .csv](https://community.naturalcapitalalliance.org/uploads/short-url/fFEqNGT8N2h9vw6loXbfZ20TmiT.csv) (2.0 KB) ---

Thanks for that table. It looks like there is one habitat missing from the “info” table that is present in the “criteria” table: “RPL”. You can decide if that habitat should appear in both tables, or in neither. And we should update the model’s validation to give a more informative error message about that. After resolving that, I expect you will encounter a very similar error that states: `The following stressor-habitat pair(s) do not have at least one **consequence** rating:` I noticed that all the criteria are labelled “E” for exposure. At least one in each habitat-stressor pair will need to be a “C” consequence criteria. There is some guidance for these criteria in the User’s Guide. [Habitat Risk Assessment — InVEST documentation](http://releases.naturalcapitalproject.org/invest-userguide/latest/habitat_risk_assessment.html#exposure-and-consequence-criteria-in-more-detail) Good luck, ---

Thank you so much for the insight! I’ll check it out and fix it as appropriate. The reason I included “Es” for all criteria is that I just wanted to test the output before going ahead with the actual correct criteria. Thanks again! ---

Hi Dave, Your solution worked just fine. However, I encountered another problem that I cannot understand. Is there something wrong with one of my shapefiles? AttributeError: ‘NoneType’ object has no attribute 'SimplifyPreserveTopology You may find the data log here: [InVEST-Habitat-Risk-Assessment-log-2021-09-21–09\_37\_41.txt](https://community.naturalcapitalalliance.org/uploads/short-url/5B7gyirwS3ePhTIrZzDpOmbUxFh.txt) (11.3 KB) Thank you for all your help ---

Once I removed my roads shapefile, the model finally worked. So there has to be a problem with this shapefile, although I can’t figure out what I may be. ---

Hi @kurapika , great to hear you are making progress. > AttributeError: ‘NoneType’ object has no attribute 'SimplifyPreserveTopology My guess is that this error indicates a feature in the Roads shapefile that has no actual geometry. You can probably find & delete that feature (or add some geometry to it) in GIS with a conditional selection expression; something like “geometry is NULL”. It will vary depending on what GIS software you are using. ---

That makes sense. Thank you for all your help! ---
