Typescript error on latest version when `--isolatedModules` is set to true.

[Carmelle Millar]

We're on version "@contentful/node-apps-toolkit": "^2.0.2",.

Our Typescript config has "isolatedModules": true /* Transpile each file as a separate module (similar to 'ts.transpileModule'). */,

We see the following error locally and on CI:

node_modules/@contentful/node-apps-toolkit/lib/requests/typings.d.ts:43:6 - error TS2748: Cannot access ambient const enums when the '--isolatedModules' flag is provided.

43     [ContentfulContextHeader.AppId]: string;
        ~~~~~~~~~~~~~~~~~~~~~~~

node_modules/@contentful/node-apps-toolkit/lib/requests/typings.d.ts:49:6 - error TS2748: Cannot access ambient const enums when the '--isolatedModules' flag is provided.

49     [ContentfulContextHeader.UserId]: string;
        ~~~~~~~~~~~~~~~~~~~~~~~

node_modules/@contentful/node-apps-toolkit/lib/requests/typings.d.ts:56:6 - error TS2748: Cannot access ambient const enums when the '--isolatedModules' flag is provided.

56     [ContentfulContextHeader.SpaceId]: string;
        ~~~~~~~~~~~~~~~~~~~~~~~

node_modules/@contentful/node-apps-toolkit/lib/requests/typings.d.ts:57:6 - error TS2748: Cannot access ambient const enums when the '--isolatedModules' flag is provided.

57     [ContentfulContextHeader.EnvironmentId]: string;

Typescript is offended by the following lines in typings.d.ts:

export declare type AppContextSignedHeaders = {
    [ContentfulContextHeader.AppId]: string;
};
export declare type SubjectHeadersUser = {
    userId: string;
};
export declare type UserContextSignedHeaders = {
    [ContentfulContextHeader.UserId]: string;
};
export declare type Context<SubjectContext> = {
    spaceId: string;
    envId: string;
} & SubjectContext;
declare type SignedHeadersWithoutSubject = {
    [ContentfulContextHeader.SpaceId]: string;
    [ContentfulContextHeader.EnvironmentId]: string;
};

In particular, ContentfulContextHeader.

I believe it is complaining that ContentfulContextHeader might not be accessible.

I found an article that seems to sum up the issue: https://ncjamieson.com/dont-export-const-enums/

Would Contentful be able to fix this ASAP? This is a blocker for development.

Thank you!
