Hey all Pickaxers,
I’m hoping someone can help me with an issue I’ve been having.
I’ve created a self-service ticketing system, and I’m able to collect all relevant details, which are sent in a webhook payload to N8N (all working fine).
The issue starts when I start introducing images/files into the mix, I cannot get Pickaxe to release the image URL at the end of the customer’s conversation (webhook). The only way I’ve been able to get this to unlock and pass the URL in the webhook is at the point of upload, and I specifically ask to “send the image to the webhook” for some reason, it seems like the temporary link (URL) doesn’t cache and is not available later. If I prompt and ask for the file URL to be show directly in the chat then this doesn’t provide the actual link and access is denied.
This is really key for my Pickaxe project as I need customers to be able to upload proof of their issues and this needs to be sent in the final payload to our internal customer service team, any help to fix this issue will be greatly appreciated, I have thought of keeping a directory of all uploaded files and tag any upload with “userId” and “conversationId” to track back but this isn’t ideal, I have also tried the environment variables but I can’t get this to work either.
Below is the action code I have been playing about with -
