Shopify API Issues. Please call the .initialize() method to setup your app context object

Topic summary

Node app built with Shopify CLI starts compiling but crashes at runtime with an internal server error after adding the Shopify Node.js library for the REST Admin API.

Key issue:

  • CLI logs show: “Context has not been properly initialized. Please call the .initialize() method to setup your app context object,” originating from @shopify/shopify-api via @shopify/koa-shopify-auth.

Troubleshooting / viewpoints:

  • The original poster suspects a conflict between koa-shopify-auth and other Shopify packages but doesn’t have clear steps to fix it.
  • A reply suggests reviewing the official koa-shopify-auth “usage” instructions on GitHub as a likely path to proper initialization.

Status:

  • No confirmed resolution yet; the thread ends with a pointer to documentation rather than a concrete fix.

Ive setup a basic node app using Shopifys CLI and was trying to add REST Admin API to the project.

I went to https://shopify.dev/api/admin-rest#client_libraries and installed the Shopify Node.js library package through my CLI. However the issue is: Now that I compile the app, it will say that it compiles successfully however upon opening the app, it comes up as a internal server error and this is the output from the CLI

Error: Context has not been properly initialized. Please call the .initialize() method to setup your app context object.

Any way to resolve this? Ive seen other posts that KOA-shopify-auth is conflicting with the packages, however no proper steps were mentioned in resolving the issue.

Hi Jaons,

I’m not too familiar with the koa-shopify-auth library, but these usage instructions might help. Have you seen them before?
