Error on Deno1.30.1

[f1w3]

While I was using this library, I encountered a problem that I couldn't solve.

const client = new Client({
    token: token,
    replId: replId
})
await client.connect()

The following error occurs when executing

not implemented: ClientRequest.setTimeout
error: Uncaught Error: Unexpected token 'P', "POST body "... is not valid JSON

I understand that I shouldn't use deno, but I can't fix it myself (and I don't know the cause of the error), so I opened an issue

[rayhanadev]

How curious, while yes this library is built for Node.js and not Deno, the error doesn't seem to be with crosis4furrets itself, but a library it consumes (that I made) called @rayhanadev/replit-gql which is a wrapper around Apollo Client GraphQL but uses patched headers and node-fetch so it'll work on server.

I'm not quite sure what the error is there, it might be work looking into how @apollo/client and node-fetch behave in Deno. If I do come across a fix I will implement it!

[rayhanadev]

Presumably, this could be fixed by altering my GraphQL library and crosis4furrets into using their Web API equivalents because those are available in Deno... will see what I can do 😆.

I have located where the problem is occurring.
In @rayhanadev/replit-gql, in dist/index.mjs, at line 2112:25

}

seems to be the problem
If I check the variable bodyText

POST body missing, invalid Content-Type, or JSON object has no keys.

I found that the above error occurs because the above characters are stored and JSON.parse() is used to parse them.
