Hello,
I am struggling with using the ArcGIS Attachment Connector to upload multiple attachments in an ArcGIS Online Feature Service
I am able to add one attachment but for some reason it will not add multiple photos.
This is for a Survey123 that I set up an automation in FME Flow with webhook to add certain features to a hosted feature layer in ArcGIS Online. It runs fine, adds the data, but the moment there is more than 1 photo that needs to be attached, it only uploads 1 photo. Any advice would be greatly appreciated. Thank you!
Edit: This works perfectly fine on the workbench (it will add all attachments) but when I try to run it on flow, it will only add 1 attachment.
I do receive the following error message:
