the imports are not properly generated for customFetch which fail running in docker environment

[xmlking]

I am using customFetch and additionalEnvelopPlugins with scripts pointing in my src as shown below.
everything works fine locally, but when I am doing docker build, I am getting import path error for customFetch

This works in local run i.e, npm run dev but when dockerized and run, it is failing with path issues for customFetch

Workaround: I have to use this during docker build to make it work. (obviously not going to work for local run)

Note: additionalEnvelopPlugins has no issues.

I think the root cause is how imports are generated in .mesh/index.ts

Could you create a reproduction repo? Thanks!

Could you create a repo so we can run and reproduce?

[xmlking]

@ardatan sorry for the delay. here is the repo to reproduce this issue

To reproduce error, run:

git clone https://github.com/xmlking/graphql-mesh-specific 
cd graphql-mesh-specific 
pnpm i
pnpm build
pnpm start

Error

💥 🕸️  Mesh Error: Cannot find module './src/middleware/custom-fetch.ts'
Require stack:
- /graphql-mesh-specific/.mesh/index.ts

This should work without error

pnpm dev

I debugged this a bit and the issue is basically here:

https://github.com/Urigo/graphql-mesh/blob/30ecdbde782acf9b33e35805bc0f7deacbf4b038/packages/config/src/utils.ts#L103

which then calls:

https://github.com/Urigo/graphql-mesh/blob/30ecdbde782acf9b33e35805bc0f7deacbf4b038/packages/config/src/utils.ts#L66

A very hacky fix:

const relativeModuleName = cross_helpers_1.path.isAbsolute(moduleName) ? (type === 'fetch' ? `../${name}` : moduleName ) : moduleName;

I don't have time to dedicate to finding all the ways this (or a better fix) could break things (i.e. a proper solution).

For now, I'll likely sed my way out of this but maybe this helps someone more knowleadgeable to fix this quicker.

Btw this doesn't only affect docker environments. This happens calling yarn run mesh build.
