I made a workbench which takes a .zip folder as a source, which contains .csv files, and sometimes an 'attachment' folder which contains images or videos. The output is an xlsx file, a dxf file and if there is an 'attachment' folder, this 'attachment' folder.
This workbench will be used through a workbench app in FME Server, the xlsx and th dxf data can be retrieved from the 2 featurewriters via the data downlaod service, but I have no idea of how to read and write a folder with file extensions I can't know. The only solution I see is to move the folder.
So I made a python script which unzip the entry file, check if there is a 'attachment' folder, and if so, move it to 'FME_SERVER_DEST_DIR', so it can be downloaded from the url with the xlsx and the dxf.
Here's my problem. With a .zip file with only .csv file and no 'attachments' folder, there is no problem, I get my url to download the data and I get the xlsx and the dxf. But if there is a 'attachments' folder, the workbench is completed, no failure, but I do not get a download url.
