UID param not passed into the template page query? about gatsby-source-prismic-graphql HOT 19 OPEN

@elkorn could you please reopen the issue? I tried with both:

• following write-up from https://prismic.io/docs/reactjs/getting-started/prismic-gatsby
• cloning the "arnaud" example https://github.com/birkir/gatsby-source-prismic-graphql/tree/master/examples/arnaud

and I am also seeing an empty edges array. The query runs fine in GraphiQL (with query variables) but as you mentioned in #47 (comment), the uid property is empty in pageContext.

I can also confirm than the last version the query runs properly is 2.8.8 (from @brandonfancher #32 (comment)). After that, the edges array is empty.

Upgrading gatsby-source-prismic-graphql to 3.4.0-beta.2 did fix the problem for me.

Good question.

Only thing I can think of is a case where its just the preview page.

https://github.com/birkir/gatsby-source-prismic-graphql/blob/master/packages/gatsby-source-prismic-graphql/src/gatsby-node.ts#L132

Also, you can check with the lang paramter

heisenbug. Started working for no apparent reason. I deleted the cache multiple times so I don't think it was that which helped. As far as I was able to see from digging in - the plugin was actually passing the uid correctly into createPage, but it didn't come out to pageContext in WrapPage.

Closing for now, I'll reopen if I have any new information.

I'm having the same issue, queries return empty results as if uid is not being passed in, even though I've verified it is being set in gatsby-node.js from this plugin.

My page component:

import { graphql } from "gatsby"
import * as React from "react"
import Layout from "../components/layout"

export const query = graphql`
  query Page($uid: String!) {
    prismic {
      page(uid: $uid, lang: "en-us") {
        title
        body
      }
    }
  }
`

const Page = ({ data }) => {
  console.log(data)
  return (
    <Layout>
      <h1>Test page....</h1>
    </Layout>
  )
}

Page.query = query

export default Page

and my gatsby-config.js contains:

    {
      resolve: 'gatsby-source-prismic-graphql',
      options: {
        repositoryName: `puppet`, // (required)
        accessToken: `12345`, // (optional)
        path: `/preview`, // (optional, default: /preview)
        previews: true, // (optional, default: false)
        pages: [{ // (optional)
          type: `Page`,         // TypeName from prismic
          match: `/page/:uid`,  // Pages will be generated under this pattern (optional)
          path: `/page`,        // Placeholder page for unpublished documents
          component: require.resolve('./src/content-types/page.js'),
          lang: `en-us`
        }],
      }
    },

But all I get back in my component is:

{
  data: {
    prismic: {
      page: null
    }
  }
}

The query works fine in GraphiQL so I don't think there's any problem with that, just not returning any data from the PageQuery for some reason.

I've tried this with previews enabled and disabled and had the same problem either way.

I'm also running into the same issue @elkorn and @mikeyp, and it looks like rolling Gatsby back to 2.3.17 fixes the issue for now.

See here: #32 (comment)

from gatsby-source-prismic-graphql.

Also running into this issue, however, Gatsby 2.3.17 did not fix the issue for me. @mikeyp any luck in the end?

from gatsby-source-prismic-graphql.

Having the same problem. When running gatsby develop, the uid does not get passed to the GraphQL query. If doing gatsby build however, everything does work.

EDIT: now seems to work using gatsby 2.13.51 and gatsby-source-prismic-graphql 3.3.1.

Reopening the issue for @mlbrgl.

I am having this issue as well. Has anyone come up with a temporary workaround?

Having the same issue here UID is not being passed to the page templates

from gatsby-source-prismic-graphql.

same issue, and fixed by upgrading to the 3.4.0-beta.2 (thanks @ascii-husky!)

from gatsby-source-prismic-graphql.

Thanks for the tip @ascii-husky, upgrading made it work for me as well.

Hello everyone,

Got the same issue with :
"gatsby": "^2.17.6",
"gatsby-source-prismic-graphql": "^3.3.1",

updated to below and worked :
"gatsby": "^2.17.10",
"gatsby-source-prismic-graphql": "^3.3.1", (no changes)

from gatsby-source-prismic-graphql.

Had the same exact issue as vincent-wantomo, and updating to gatsby 2.17.10 did the trick for me also, in case anyone doesn't want their source plugin to be on a beta version

from gatsby-source-prismic-graphql.

Thank god, was going insane thinking I did something wrong. Can confirm that upgrading Gatsby passes uid correctly now.

from gatsby-source-prismic-graphql.

Looks like it's not working with useStaticQuery though.

Lost a couple of hours on the same issue, upgrading gatsby from 2.17.4 to 2.19.17 solved it. Thank you 👍
