I have a csv file with a headerrecord and some datarecords. What i’m trying to esteblish is to store the data in a MSSQL database. Therefore I read the file using the flatfile adapter and then used an iteration to map the corresponding fields and store the data in the database. The iteration expension node expects an array as input, but I only have the flatfile with flatfile records. if I connect the flatfile to the expension node, I get the following errors: 03.10.2018 11:20:44 The object flow ending in the input expansion node ‘claims’ does not result in an Array. 03.10.2018 11:20:44 Expansion nodes must have arrays as in- and outputs.
