Cannot find module 'graphql-auto-transformer'

[pcvvelzen]

After following the installation instructions (step1) with npm install and (step 2) adding graphql-auto-transformer to the transform.conf.json file of my Amplify API:

{
    "Version": 5,
    "transformers": [
        "graphql-auto-transformer"
    ]
}

When attempting to use @auto directive in my model

type Post @model {
[...]
    createdAt: AWSDateTime! @auto
}

I get the following error

$ amplify push -y
- Fetching updates to backend environment: dev from the cloud.
√ Successfully pulled backend environment dev from the cloud.

Unknown directive "auto".
An error occurred during the push operation: Unknown directive "auto".

When removing the @auto directory from my schema and running amplify push -y I get the error that graphql-auto-transformer module could not be found, while the module is present in .\node_modules\graphql-auto-transformer (after being installed through npm as mentioned in the readme.MD).

This was only resolved through installing the package globally: npm install graphql-auto-transformer -g.

Note: I am not certain as if this issue is related to this package, or to the Amplify CLI perhaps containing a bug in combination with Windows, with finding the correct relative path to ./node_nodules/graphql-auto-transformer

Did you try export NODE_PATH=./node_modules ? https://github.com/hirochachacha/graphql-auto-transformer#4-export-node_path

[hirochachacha]

let me know if the issue persists

I did have to run npm i -g graphql-auto-transformer in the build step to get it working.

How do you add this to build step?
