https://community.esri.com/t5/arcgis-pro-questions/archydro-tool-not-recognizing-visible-field/m-p/1649451#M98836 <P>I am running the Drainage Connectivity Characterization tool and have gotten the same error message several times in a row:&nbsp;</P><PRE><SPAN class="">Error processing drainage boundary with HydroID 228079.</SPAN></PRE><PRE><SPAN class="">('line 386', 'c:\\program files\\arcgis\\pro\\Resources\\ArcToolbox\\Scripts\\ArcHydro\\drainageconnectivitycharacterization.py', "RuntimeError: Cannot find field 'FType'")</SPAN></PRE><PRE><SPAN class="">Error processing drainage boundary with HydroID 228080.</SPAN></PRE><PRE><SPAN class="">('line 386', 'c:\\program files\\arcgis\\pro\\Resources\\ArcToolbox\\Scripts\\ArcHydro\\drainageconnectivitycharacterization.py', 'TypeError: fields size must match size of the row')</SPAN></PRE><P>&nbsp;</P><P>The message continues for every drainage boundary in the feature class (658 total), saying "TypeError: fields size must match size of the row" each time, and only "Cannot find field 'FType'" for the first message. I've put the field "FType" in every feature class it could possibly exist in (Hydroedge, Boundary Drainage Link, Drainage Boundary) and the tool is still not recognizing the field and returns the same message. I'm not sure what else I can do to resolve this besides starting the workflow over. Is there a solution I'm missing that might help? I've attached my inputs as a screenshot below.&nbsp;</P> Wed, 10 Sep 2025 17:43:36 GMT JustinKeller1 2025-09-10T17:43:36Z https://community.esri.com/t5/arcgis-pro-questions/archydro-tool-not-recognizing-visible-field/m-p/1649451#M98836 <P>I am running the Drainage Connectivity Characterization tool and have gotten the same error message several times in a row:&nbsp;</P><PRE><SPAN class="">Error processing drainage boundary with HydroID 228079.</SPAN></PRE><PRE><SPAN class="">('line 386', 'c:\\program files\\arcgis\\pro\\Resources\\ArcToolbox\\Scripts\\ArcHydro\\drainageconnectivitycharacterization.py', "RuntimeError: Cannot find field 'FType'")</SPAN></PRE><PRE><SPAN class="">Error processing drainage boundary with HydroID 228080.</SPAN></PRE><PRE><SPAN class="">('line 386', 'c:\\program files\\arcgis\\pro\\Resources\\ArcToolbox\\Scripts\\ArcHydro\\drainageconnectivitycharacterization.py', 'TypeError: fields size must match size of the row')</SPAN></PRE><P>&nbsp;</P><P>The message continues for every drainage boundary in the feature class (658 total), saying "TypeError: fields size must match size of the row" each time, and only "Cannot find field 'FType'" for the first message.
