[gatsby-source-medium] TypeError: Cannot read property 'filter' of undefined

[kbrgl]

I'm trying to use gatsby-source-medium with a user account. Publications work fine, but I get an error with user accounts. The API response doesn't seem to possess payload.posts, which gatsby-source-medium expects.

gatsby develop outputs the following:

success delete html files from previous builds — 0.012 s
success open and validate gatsby-config.js — 0.005 s
success copy gatsby files — 0.024 s
success onPreBootstrap — 0.018 s

Here's my gatsby-config.js

const metadata = require('./metadata')

module.exports = {
  siteMetadata: {
    ...metadata,
  },
  plugins: [
    'gatsby-plugin-react-helmet',
    {
      resolve: 'gatsby-plugin-typography',
      options: {
        pathToConfigModule: 'src/utils/typography.js',
      },
    },
    {
      resolve: 'gatsby-source-medium',
      options: {
        username: '@kbrgl',
      },
    },
  ],
}

Reproducing

Change the username from smartive to an actual username (e.g. @kbrgl) in gatsby-config.js of the using-medium example

Hello @kbrgl Could you please build a small reproduction site for us to check out and upload to a Git repo ? That way it's way quicker to reproduce your error and solve it ;)

This feels related - I can't actually retrieve info. I'm only trying to get my stories from my own medium account. I get this error:

success delete html files from previous builds — 0.006 s
success open and validate gatsby-config.js — 0.004 s
success copy gatsby files — 0.058 s
TypeError: Cannot convert undefined or null to object
    at _callee$ (C:\Users\Perry\Desktop\perrysetgo30\tutorial-part-one\node_modules\gatsby-source-medium\gatsby-node.js:62:37)

This is my gatsby-config.js

[...]
  plugins: [
    {
      resolve: `gatsby-source-filesystem`,
      options: {
        name:`src`,
        path: `${__dirname}/src/`,
      }
    },
    {
    resolve: `gatsby-source-medium`,
    options: {
      username: `@perrysetgo`
      }
    },
[...]

Some logging around line 62 of the gatsby-node.js for the plugin seems to suggest that json.payload.references.Collection is not a thing - but I don't know this API well enough to really debug from here. Any help would be super appreciated getting this to work.

I'm really enjoying working with gatsby, it's awesome and making things come together for my new site build so fast!

@PerrySetGo simple reproduction sites are the best way to get help 👍 this is a new source plugin so not well tested yet.

[kbrgl]

Okay, I have a repo up at kbrgl/gatsby-issue-2291 to reproduce. (It's just the using-medium example with the username line changed to a user account).

[ptcampbell]

Did you find the answer to this one? Came across the same problem.

[kbrgl]

@ptcampbell nothing so far

[KyleAMathews]

Looks like this PR fixes this issue perhaps? #2515

Would love feedback on the PR from some people in this issue!

[kbrgl]

@KyleAMathews that does seem like a fix. I'll try it out.

[amandeepmittal]

I am getting the same error. Any fix for it?

[aaronklaser]

try changing @ to %40

[KyleAMathews]

Fixed in #3623
