Create Overland Flow Connectors - Weird Line Error

[MichelleTanner]

Hello,

I am new to ArcHydro and trying to work through the stormwater processing steps. When I get to the Create Overland Flow step, I get some weird errors back, and all of the overland flow lines are starfished out from HydroJunction Object ID 1. 

Does anyone know why this error happens?? How can I fix it? Thanks for the help. I've attached a map example plus the geoprocessing results.

Which version of ArcGIS are you using? 10.6.1? Have you installed the Spatial Analyst Patch for ArcGIS?

Michelle, did you end up resolving this?  I've just encountered the same error (I have desktop 10.7.1)

[MichelleTanner]

I don't think I did.. and I was using the most recent version of ArcGIS at the time

[lizannewilmot]

so did you just not complete the model?

did you run it again and it worked?

or were you just stuck at the overland connectors?

I got stuck at the overland connectors. I ended up abandoning this project due to the errors in ArcHydro.. Perhaps Christine Dartiguenave‌ has another fix?
