It’s difficult to debug custom actions in Adalo. Did you try to run this action manually (for instance, from Postman) and see what happens?
Also did you check Cloudinary logs if they show something?
In the first place, I think that people who use adalo are often not engineers.
We pay for the service instead of not being able to do the difficult things.
It is very troublesome to be unable to do what was done.
I fully understand your frustration when something doesn’t work as expected (or as worked before).

As for your exact problem (you say that custom action stopped working), if I had it, I would do the following:
check custom action in Adalo by running it in the app builder. See if the results of actions are successful or not and what is returned by Cloudinary.
if custom action doesn’t work in Adalo and Cloudinary return some error - see what is written there and check Cloudinary documents.
try to simulate the request to Cloudinary from 3rd party software like Postman and see if it works or not.
the most difficult part will be when Adalo custom action works ok, but image isn’t uploaded in the app itself (from app preview, for example). The most common case is malformed JSON in a custom action - for example, some parameters are missing. This requires case-by-case investigation.
I thought you were a person inside adalo, so I replied like a complaint. I’m sorry if I made a mistake.
I don’t know what to write here, but sending a support ticket to adalo is almost ignored. I understand that it is operated by a small number of people, but I would like some reply.
For example, the reply may be “Give up because it is impossible”.
