Are you sure the id of that receiving collection is `main_collection`?

Try printing out what is returned from an empty `msg.url()` in all of your scripts.

```lua
print(msg.url())

```

It should show you exactly what the url of each script is, and you can use it to verify your addresses.

I have used that in the recieving script and copied and pasted the url into the msg.post for the script i am trying to send from and it still gives the same error unfortunately.
