what is this piece of code doing?
and Why are we using Ezjsonm.to_string body if the above expression is already converting the query to string form.??

[gs0510]

In this the json object is being constructed, so body is still an ezyjsonm type which is why you still need to convert body to a string type for sending the post request in line 38.

Also, if you do an opam install ocamlformat and run dune build @fmt --auto-promote . it will format the code so it's more legible. :)

Hii @patricoferris, can you please help me resolve this.

[patricoferris]

As @gs0510 quite rightly mentioned Ezjsonm.to_string in converting our value to a JSON string, this can be transferred over the internet to the API.

I suggest having a play around with it in utop for example:

utop # Ezjsonm.to_string (`O ["hello", `String "world"]);;
- : string = "{\"hello\":\"world\"}"

Most GraphQL APIs (afaik) understand the body as a JSON object where they query is stored as a value associated with a key called query (there are other things you can add to like variables etc.) so that's what we're doing in that part of the code:

{
  "query": "query { ... }"
}

Also as a general rule it is pretty bad to commit API keys into any code. Other people could abuse it but the blame may come back to you since it is your API key. I don't think anyone here would do that of course, but just letting you know :)) You probably want to disable that API key and generate a new one.

Thanks, @gs0510, @patricoferris, I understood the use of Ezjsonm.to_string and I will generate a new API Key.
But I am still getting the error of no query string present.

. :((.

I think the error is caused due to the presence of arguments inside the query but I don't know how to resolve that. Plse kindly look into this and help me.
