Typescript Error after update to apollo-server-express 2.11.0

[andreastoermer]

I update apollo-server-express package from 2.10.1 to 2.11.0 and during the build process of the application I get the following Typescript error message:

node_modules/@apollo/gateway/node_modules/apollo-cache-control/dist/index.d.ts:24:9 - error TS2717: Subsequent property declarations must have the same type.  Property 'cacheControl' must be of type '{ setCacheHint: (hint: CacheHint) => void; cacheHint: CacheHint; }', but here has type '{ setCacheHint: (hint: CacheHint) => void; cacheHint: CacheHint; }'.

     24         cacheControl: {
                ~~~~~~~~~~~~
     'cacheControl' was also declared here.

When I return back to version 2.10.1, everything is ok.

Same over here. Deleting node_modules and package-lock.json and reinstalling didn't work.
Everything is on latest available Version.

Edit: resolved by upgrading apollo-server-plugin-response-cache to 0.4.0.

I'm seeing this issue even with apollo-server-express on version 2.10.1.

$ `yarn bin`/tsc

@andreastoermer Could you try and confirm whether the suggestion by @chrislambe resolves it for you and close this if so? Thanks!

[thenameisangel]

@andreastoermer @bke-daniel Did you guys end up resolving this issue? I'm experiencing similar issues on version 2.12.0.

[abernix]

@thenameisangel What is the output you receive when you run npm ls apollo-cache-control?

[andreastoermer]

I can only fix the current problem, when I set SkipLibCheck to true in tsconfig. But that's only my workarround (and not a good one). When I set it to false, I get the error again (with 2.12.0)

[bke-daniel]

Adding apollo-cache-control manually to package.json with version 0.10.0 fixes the issue.

[thenameisangel]

@abernix I ran npm ls apollo-cache-control and noticed that that apollo-cache-control version in the apollo-server-core subdirectory was 0.9.1 while the other apollo-cache-control packages were 0.10.1. I did a global uninstall of apollo-server-core and re-installed the package, and it resolved the issue. However, this failed once I push my changes upstream, as the CI/CD pipeline that runs on my upstream branch simply runs a npm install and doesn't install each package individually.

I tried @bke-daniel's suggestion of manually adding apollo-cache-control version 0.10.0 in the package.json, cleared the node modules, and ran npm install again, and this resolved the issue. Thank you guys for the help!

FYI I had the same issue updating from apollo-server@2.13.0 to apollo-server@2.13.1.

Fixed by installing apollo-cache-control@^0.10.1-alpha.0.

@abernix Is it correct that apollo-server-core 2.13.1 references a lot of alpha dependencies?

apollo-server-core@^2.13.1:

[bke-daniel]

@marcoreni Correct, due to the version bumps it needs to be apollo-cache-control@0.10.1-alpha.0 by now.

Still an issue with 0.11.1?

[Huljo]

Having the issue with 0.11.1.
Adding apollo-cache-control@0.10.1-alpha.0 is not fixing the problem in my case.
@marcoreni did you just changed "apollo-cache-control": "0.10.1-alpha.0" to your apollo-server-core package.json ?
Our CI is still failing due to this issue.
yarn list apollo-cache-control
└─ apollo-server-core@2.14.3
└─ apollo-cache-control@0.11.0

[munjalpatel]

Also having the same issue:

npm ls apollo-cache-control

backend@0.0.1 /Users/.../backend

│ └─┬ apollo-server-core@2.16.1
│   └── apollo-cache-control@0.11.1

[glasser]

So TypeScript supports module augmentation and interface merging. It claims that:

Non-function members of the interfaces should be unique. If they are not unique, they must be of the same type. The compiler will issue an error if the interfaces both declare a non-function member of the same name, but of different types.

But for some reason it thinks the additions to GraphQLResolveInfo in apollo-cache-control are not "the same type". I'm not sure if this is a TS bug or there's some good reason for this.

When using prereleases of npm modules, it's a lot easier to end up with two versions of a module in your node_modules tree, where your explicit use of the prerelease pulls in a whole subtree of prerelease Apollo Server modules but some other module pulls in a subtree of non-prerelease Apollo Server modules, and then you have two copies of apollo-cache-control and TypeScript gets sad.

I don't feel great about this suggestion, but one thing that does work (if you're pretty sure that the prerelease of apollo-cache-control doesn't actually differ from the released version in an important way — eg if we've only changed comments or README or something else not relevant to your lifestyle) is to add

    "baseUrl": ".",
    "paths": {
      "apollo-cache-control": ["node_modules/apollo-cache-control"]
    }

to your app's tsconfig.json. ie, to tell it only to read the top-level ACC module no matter what.

Not a compelling answer but it is working for my own app testing!

@andreastoermer

I did the same thing as you

I did the same thing as you, but this is just a temporary solution.

I tried to install an apollo-cache-control and added a package.json configuration

npm i apollo-cache-control@0.14.0

  "paths": {
    "apollo-cache-control": [
      "node_modules/apollo-cache-control"
    ]
  }

When i run: npm ls apollo-cache-control

├─┬ @nestjs/graphql@7.11.0
│ └─┬ apollo-server-testing@2.25.2
│   └─┬ apollo-server-core@2.25.2
│     └── apollo-cache-control@0.14.0  deduped
├── apollo-cache-control@0.14.0 
└─┬ apollo-server-express@2.25.2
  └─┬ apollo-server-core@2.25.2
    └── apollo-cache-control@0.14.0  deduped

But it is always ineffective. Do you have a good solution now?

[glasser]

For what it's worth, the location of this declare module moved from apollo-cache-control to apollo-server-core in Apollo Server 3, and we're moving it to apollo-server-types now (#5512). This might help a bit.

Otherwise, I think this issue mostly just happens when there are alphas out, and using the tsconfig.json / paths trick does work, so I'm going to close this for now.

[jbrainz]

i'm still having these issue even after trying to tweak the tsconfig.json file

[glasser]

npm dedup may help here. It looks like you may be mixing Apollo Server 2 with 3 (apollo-cache-control is only in AS2 and the referenced apollo-server-types line was added in AS 3.0.2).

[jbrainz]

Thanks, i was able to fix this from #3339 (comment)
