node-gtoken: 4.1.2 breaks our build with " error TS1086: An accessor cannot be declared in an ambient context."

We do not use gtoken directly and this started happening just after 4.1.2 rolled out. It seems to be a very similar issue we reported here for google-gax.

.../node_modules/gtoken/build/src/index.d.ts:32:9 - error TS1086: An accessor cannot be declared in an ambient context.

32     get accessToken(): string | undefined;
           ~~~~~~~~~~~

.../node_modules/gtoken/build/src/index.d.ts:33:9 - error TS1086: An accessor cannot be declared in an ambient context.

33     get idToken(): string | undefined;
           ~~~~~~~

.../node_modules/gtoken/build/src/index.d.ts:34:9 - error TS1086: An accessor cannot be declared in an ambient context.

34     get tokenType(): string | undefined;
           ~~~~~~~~~

.../node_modules/gtoken/build/src/index.d.ts:35:9 - error TS1086: An accessor cannot be declared in an ambient context.

35     get refreshToken(): string | undefined;

Our environment:

$ node --version
v10.16.2
$ yarn --version
1.17.3
$ tsc --version
Version 3.5.3

Workaround: In package.json add:

"resolutions": {
    "gtoken": "4.1.1"
  }
