Input code

Starting from yesterday our TS builds failed and we tracked it down to a change in the dependencies of this project.

    ERROR in /wrk/Webdesk-CompileOnly_release/node_modules/@types/gensync/index.d.ts
    [tsl] ERROR in /wrk/Webdesk-CompileOnly_release/node_modules/@types/gensync/index.d.ts(45,34)
          TS1005: ',' expected.

The solution for us was to downgrade to 7.26.7

This is what caused the problem for us:

• babel/core was depending on a library called gensync
• however with version 7.26.8 the types dependency to gensync was added as a 'normal' dependency, whereas in previous version it was just a dev-dependency.
