While trying to submit this collection’s solution I ran in to an error. I copied the “collection_uid” found under “ID” in the “Collection Details” to my environment but the request returned a 404.
How I found the problem:
I found that my mistake was that I had copied a return character by mistake. After checking the console I found
%0A at the end of my path.
Maybe this will help folks who are encountering the same error.
