The header created in scenarioimporter does not match the number of columns in the input data
Solution 1.: Check definition of delimiter in ScenarioImporter.
<Delimiter><![CDATA[;]] ></Delimiter>
<TextQualifier>"</TextQualifier>
<NotTypeConvertedDynamicColumns></NotTypeConvertedDynamicColumns>
<HeaderLine>info1;nazev;ulice;psc;město;cena_zbozi;id;nevim1;mobile;nevim2;nevim3;nevim4;email;nevim5;nevim6;nevim7;platba;nevim8;nevim9;info2</HeaderLine>
Definated Delimiter is semicolon in this example. Check delimiter in source data file and change it in config file <Delimiter><![CDATA[;]]></Delimiter>.
If you have right delimiter and mistake persists, open import file in text editor and check the real data structure.
Example:
In the picture is CSV file open in Excel:
The same CSV file open in text editor:
In text editor you can see semicolon on the end of row. It means that is free column there. (You don´t see this in Excel).
Solution 2.: Add free column in HeaderLine.
<HeaderLine>info1;nazev;ulice;psc;město;cena_zbozi;id;nevim1;mobile;nevim2;nevim3;nevim4;email;nevim5;nevim6;nevim7;platba;nevim8;nevim9;info2;</HeaderLine>
