Gatsby: Problem with gatsby-transformer-json?

[kartik2406]

Description

Gatsby JSON transformer fails even with correct config.
I used the same configuration as on https://www.npmjs.com/package/gatsby-transformer-json.
I tried this with gatsbygram and the transformer works there, am i missing something here?

Steps to reproduce

• Clone https://github.com/kartik2406/gatsby-json-test
• run gatsby develop
• Observe that you get following error and dev server does not even start
  Plugin gatsby-transformer-json returned an error TypeError: createContentDigest is not a function

Expected result

What should happen?
Gatsby server should start, should be able to retrieve data from json.

Actual result

Gatsby server fails.

What happened.
Gatsby tranformer json fails

I have been using gatsby-transformer-json 2.1.2 which works fine. After upgrading to 2.1.3 I get this

error Plugin gatsby-transformer-json returned an error 
TypeError: createContentDigest is not a function

I have rolled back to 2.1.2 for now

Oh you also need to upgrade core gatsby.

[KyleAMathews]

We should upgrade the peerDependency of transformer-json

Thanks everyone :smile: I updated gatsby and gatsby-transformer-json packages and now everything works fine.

@psnaik just run:

npm update gatsby && npm update gatsby-transformer-json

I'm experiencing problems with this plugin as well. My gatsby-config has nothing out of the ordinary in it:

{
  resolve: 'gatsby-transformer-json',
  options: {
    typeName: 'Json',
  },
},

gatsby develop crashes out with this message:

success copy gatsby files — 0.026 s
success onPreBootstrap — 0.010 s
error Plugin gatsby-transformer-json returned an error


  TypeError: createContentDigest is not a function

  - gatsby-node.js:51 transformObject

... many further warnings...

success source and transform nodes — 0.129 s
success building schema — 0.204 s
success createPages — 0.001 s
error Cannot read property 'filter' of undefined


  TypeError: Cannot read property 'filter' of undefined

If I remove all json files from my data directory the app will start (kinda defeats the purpose though!). Even a json file with just {} or [] in it causes this error.

Any suggestions would be great.

I've upgraded to gatsby 2.4.2 and v2.1.4 of the plugin.

@Vazerthon can you open a new issue with a reproduction repo and environment information?

[Vazerthon]

Thanks @kakadiadarpan, have done.

Hi there, I have just run

yarn upgrade gatsby && yarn upgrade gatsby-transformer-json

and I get the following errors when trying to run gatsby deploy

error Plugin gatsby-transformer-json returned an error


  TypeError: createContentDigest is not a function

  - gatsby-node.js:51 transformObject
    [gatsby-2-0]/[gatsby-transformer-json]/gatsby-node.js:51:26

  - gatsby-node.js:74 parsedContent.forEach
    [gatsby-2-0]/[gatsby-transformer-json]/gatsby-node.js:74:9

  - Array.forEach

and further down...

error UNHANDLED REJECTION


  TypeError: Cannot read property 'filter' of undefined

  - api-runner-node.js:274 Promise.mapSeries.catch.then.results
    [gatsby-2-0]/[gatsby]/dist/utils/api-runner-node.js:274:42

Just as before I had no error before upgrading gatsby-transformer-json

Is there any more information I can provide to help resolve this issue
