Subsequent property declarations must have the same type - cacheControl

[jasper-s]

I tried updating from v2 to v3 and keep running into the following error:

node_modules/apollo-server-types/src/index.ts:303:5 - error TS2717: Subsequent property declarations must have the same type.  Property 'cacheControl' must be of type 'ResolveInfoCacheControl', but here has type 'ResolveInfoCacheControl'.

303     cacheControl: ResolveInfoCacheControl;
        ~~~~~~~~~~~~

  node_modules/apollo-server-types/dist/index.d.ts:140:9
    140         cacheControl: ResolveInfoCacheControl;
                ~~~~~~~~~~~~
    'cacheControl' was also declared here.

It seems to be related to this change.

It seems like for some reason your TypeScript configuration is set up to load some files from node_modules/apollo-server-types/src and some from node_modules/apollo-server-types/dist: ie, both the original TS source and the generated .d.ts for the same package. This seems like a problem with your TS configuration.

If you can share a complete reproduction that allows me to see the exact error on my machine without any creativity, I'm happy to reopen and take a look.

Thank you for the response. I've been trying to figure out why that would be, and will continue that. Let me give some more information:

I have a dependency on apollo-server-lambda, and a devDependency on apollo-server.
This error does not occur in versions 3.0.0 and 3.0.1, IF I also add apollo-server-core and apollo-server-types with the respective version to my dependencies. If I do not add them, the error also occurs with 3.0.0 and 3.0.1.

So perhaps something is wrong after all that has nothing to do with my project configuration?

I encountered this issue as well, and after spending too much time searching online and debugging by building up a completely new service piece-by-piece, I finally discovered that my IDE had auto-imported import { GraphQLRequest } from 'apollo-server-types/src/index'; in one of my classes. Simply importing from apollo-server-types fixed my issue, as I just didn't pay enough attention to the original autocomplete.

Upgrading the following dependencies resolved the issue for me:

• apollo-server-core 3.1.2 -> 3.2.0
• apollo-server-types 3.1.1 -> 3.2.0

I encountered this after upgrading apollo-server to 3.4.1 from 3.
First I tried upgrading apollo-server-core to the same version, but that didn't work. Then updating both to 3.5 did work.

"apollo-server": "3.5",
"apollo-server-core": "3.5",
