typescript 3.8.3

[JustFly1984]

attaching the list of all currently existing typescript errors #22070

[JustFly1984]

doesnt work actyually!!!
found a temporary fix:

adding in package.json next lines

"resolutions": {
    "@types/reach__router": "1.2.6"
}

As I see types was updated in gatsby-link@2.3.1, but current version of @types/reach__router is 1.3.3, which also gives a conflict with @types/react

[JustFly1984]

sorry, last fix does not work anymore, cos { useLocation } does not exist on @types/reach__router@1.2.6, so I'm kind of stuck, can't run clean yarn.lock anymore, cos build fails.

Are you able to share your project or at least tsconfig? I tried to reproduce this and other TS problems ( #22706 ), but I just couldn't

[alessbell]

I just started seeing the exact same error as reported in this issue, repo is here.

Thanks @alessbell! I was able to reproduce and seems like my proposed fix in #22706 (comment) will do the trick

This should be fixed in gatsby@2.20.11 / gatsby-link@2.3.2
