BUG: onRequest returns No such file or directory

[asimpleidea]

Prerequisites

• I have checked the existing issues to ensure this is not a duplicate.
• I am running the latest version of Tailcall.

Describe the bug

Custom javascript functions/files seem not to be loaded correctly.

Steps to reproduce

Note

This also happens if you just clone the repo, and run: tailcall start jsonplaceholder_script.graphql.

1. Create this main.graphql:

schema
  # Specify server configuration: Start GraphQL server at 0.0.0.0:8000
  @server(port: 8000)
  # Specify a base url for all http requests
  @link(type: Script, src: "worker.js")
  @upstream(baseURL: "http://jsonplaceholder.typicode.com", onRequest: "foo") {
  query: Query
}

type Query {
  # Specify the http path for the users query
  users: [User] @http(path: "/users")
}

# Create a user type with the fields returned by the users api

type User {
  id: Int!
  name: String!
  username: String!
  email: String!

  # Extend the user type with the posts field
  # Use the current user's id to construct the path
  posts: [Post] @http(path: "/users/{{.value.id}}/posts")
}

# Create a post type with the fields returned by the posts api
type Post {
  id: Int!
  title: String!
  body: String!
}

2. Create this worker.js file in the same directory as main.graphql above:

function foo({request}) {
    console.log(`${request.method} ${request.uri.path}`)

    return {request}
}

3. From the same directory as main.graphql and worker.js run:

tailcall start main.graphql

you will see that the js file was successfully loaded:

 INFO File read: main.graphql ... ok
 INFO File read: worker.js ... ok
 INFO N + 1 detected: 1
 INFO 🚀 Tailcall launched at [127.0.0.1:8000] over HTTP/1.1
 INFO 🌍 Playground: https://tailcall.run/playground/?u=http://127.0.0.1:8000/graphql&utm_source=tailcall-release&utm_medium=server

4. Go to https://tailcall.run/playground/?u=http://127.0.0.1:8000/graphql&utm_source=tailcall-release&utm_medium=server
5. Launch this query:

query {
  users {
    id
    name
    posts {
      title
    }
  }
}

the returned response will show that worker.js was not actually loaded:

{
  "data": null,
  "errors": [
    {
      "message": "Worker Error: Error: IO Error: No such file or directory (os error 2)",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ]
    }
  ]
}

6. From the console you can see:

ERROR error=Worker Error: Error: IO Error: No such file or directory (os error 2)

Expected behavior

The response should not contain an error.

The console should print GET something....

Actual behavior

An error is shown that worker.js was not actually loaded.

Logs

I am unable to reproduce the error

I copy pasted the graphql config and worker.js and kept it in the same directory. And it works just fine.

Can you provide some more context?

edit: I think it might be a simple error in the location of files..

[asimpleidea]

Thank you for your reply!

I just tried cloning the repo and then running tailcall start jsonplaceholder_script.graphql.

and then just running the user query. Same thing happens to me.

[ssddOnTop]

got it.. I think you are running it in different dir like

../target/debug/tailcall ... so the root dir is something else and there's an error in resolving path

[ssddOnTop]

I think you are running it in different dir like

@asimpleidea my assumption seems to be incorrect.. it's still working in the case where binary is located in some other dir

@asimpleidea Might be something with your working dir. I tried and it worked for me -

I am able to reproduce it @asimpleidea Let me take a look. Thanks for point it out.

I've noticed that running the tailcall start command works when executed from a directory above the target file:

tailcall start ./examples/jsonplaceholder_script.graphql

However, when changing into the examples directory and running the command:

cd examples
tailcall start jsonplaceholder_script.graphql

it results in the error described in this issue.

Thank you! I would try to fix this myself but I discovered the project just today so I am not very familiar with its code yet
