Unable to use data I get via webhook

How To
1

Hi Makers.

I’m trying to get an image file via a webhook (raw data, not a URL) and then use it to send to GPT / save to drive, etc.

I am able to get the data correctly, but then when I’m trying to pull it from the webhook into GPT or any other module it throws an error saying it’s empty.

  1. I can see that the data is correctly received by Make
  2. I tested with an external webhook tester and the data is perfectly sent and received

Spoke with a few automation experts, and no one is able to figure this out. What am I doing wrong? How can I pull the “data” part (the image) and send it to GPT?

I tried directly, via iterator, other modules - all fail and throw the same error / show that the data I’m trying to pull is empty. Seems that I’m not pulling it correctly.

Attached screens.

Hope someone here knows how to solve this. I will be forever grateful.

Hey Ari,

in the first screenshot photos is a collection and not an array, but is named the way an array would be. Also tags is a text string but also named the way an array would be. What is sending this webhook? Do you have a way to verify at the other end what is being sent and how?

Thanks for the reply Stoyan. Appreciate you.
The data is sent by an app I cerated with Lovable. I’ve tested the data with an online webhook test and everything works perfectly - it’s received correctly, both the photo and the tags.

I’m not sure what to do here, it’s like I don’t know how to “use” the data that’s received via the webhook. How to access it / convert it.

Is there a way to access a collection? or should I adjust the Lovable app to send the data in a different way that would be easier to “digest” with Make?

The thing is that I can’t save the photos that I’m sending from Lovable, and I have to send the raw data of the photo and sometimes there will be multiple photos sent, so I do need to take into account a situation where there are multiple photos sent and I’ll need to iterate between them and analyze each one.

Curious to hear your thoughts. And thanks again.

Can you share the output of the webhook as a JSON?

Ok it looks like the problem is indeed the after photo. Can you update what ever is sending the webhook and rename that to just “photo”?

no no it’s just the parsing of the text here. It’s actually a “[” “]”, basically an array.. not sure why you see the textbox here in the comments.

But the variable it self is not an array, its a collection. This is causing the issue. Either change it to an array or rename it so its not confusing.

eventually solved it by making Lovable sending the data as Base64 and then turning it back to raw data after I receive it in Make, and it worked. Super weird because it couldn’t use the original raw data, but it is what it is..
