Hi @alona,
I see no error. Read the instruction below the URL field. You should not pass the full URL, only the path after the base URL.
Cheers,

Welcome to the Make community!
You inserted an Absolute (full) URL into the URL field.
If you read the description below it, it says:
Enter a path relative … for example …
So you simply need to omit the first part of the URL that will be added for you.
Hope this helps! Let me know if there are any further questions or issues.
