Thanks for reaching out!
Currently, the template is designed so that the data (URL link) inserted in the field “Video Presentation URL” and images uploaded through the Uploader, are saved in the same filed “productPictureGallery” of the Product thing in the database, which is type- List of files. It means these two types of data are connected in the workflow. See screenshots below as a reference.
The first step says that if the Input (for Video presentation) is empty, then save only the pictures are uploaded through the Uploader.
The second step says that if this input is not empty then save the URL in the database- productPictureGallery
Because of that, deleting the input “Video Presentation URL” may cause errors in the workflow and its conditions. That’s why I would not recommend deleting the duplicated action with the “Only When”, even not to delete the conditions “Only when” in the other actions.
I’m afraid, I cannot provide the exact working solution on this matter, because it’s more related to custom implementation rather than template functionality. Anyway, please try to play with these fields, maybe have to change the database structure in order to let the data save correctly and be used as needed.
Hope this helps!
