I cannot figure out why I keep getting this "StopIteration: iteration not started"error. I have confirmed the feature class 'vriTHLB_eliminated' exists and has records and all required fields.

Here is a simplified version of my code:

    fieldList = ["SPECIES_CD_1","area_ha"]
    with arcpy.da.UpdateCursor(vriTHLB_eliminated,fieldList) as cursor:` 
        for row in cursor:
        if row[0] == None or row[0] == "":  # If species 1 is null / absent / or empty string;
             cursor.deleteRow()             # delete these rows, they do not help with analysis.

        cursor.updateRow(row) #this definitely does need to indented inside the loop like this
    del row, cursor
