Variable "$skip" of required type "Int!" was not provided. #40

Closed kinnikumegane closed 4 years ago

kinnikumegane commented 4 years ago

Hello all,

can anybody help me to fix the error "Variable "$skip" of required type "Int!" was not provided." ?

I followed instruction below; https://www.gatsbyjs.org/docs/adding-pagination/

I am trying to add pagination on top page of my blog, but got stuck with error "Variable "$skip" of required type "Int!" was not provided." I got also another error "Variable "$limit" of required type "Int!" was not provided.", and I guess the cause is the same.

If somebody would kindly help me to fix it, it would be highly appreciated.

And, here is my code;

src/pages/index.jsx

import React from 'react'
import Helmet from 'react-helmet'
import { graphql } from 'gatsby'
import Layout from '../components/Layout'
import Post from '../components/Post'
import Sidebar from '../components/Sidebar'

class IndexRoute extends React.Component {
  render() {
    const items = []
    const { title, subtitle } = this.props.data.site.siteMetadata
    const posts = this.props.data.allMarkdownRemark.edges
    posts.forEach(post => {
      items.push(<Post data={post} key={post.node.fields.slug} />)
    })

    return (
      <Layout>
        <div>
          <Helmet>
            <title>{title}</title>
            <meta name="description" content={subtitle} />
          </Helmet>
          {/* commented out by kinnniku <Sidebar {...this.props} /> */}
          <div className="content">
            <div className="content__inner">{items}</div>
          </div>
          <Sidebar {...this.props} />
        </div>
      </Layout>
    )
  }
}

export default IndexRoute

We don't provide support on GitHub issues, we only take bug requests here. Sorry we didn't make that clear. I've updated the package readme to make it clearer. Please post your issue on stackoverflow. I'll close this now as it looks like a question and not a bug report. Best of luck solving your issue.
