TypeError: Cannot read property 'prototype' of undefined instead of diff

🐛 Bug Report

Jest throws a type error

TypeError: Cannot read property 'prototype' of undefined
at actual.then.result (../../node_modules/jest-jasmine2/node_modules/expect/build/index.js:176:63)

similar to reported here: #6730

To Reproduce

The test

return expect(
    mutate({
        query: MUTATION_INVITE_MEMBERS,
        variables: {
            id: defaultGroup.id,
            input: { ids: [otherSocialUser.id] },
        },
    }),
).resolves.toMatchObject({
    data: {
        social__inviteMembers: [
            {
                user: {
                    id: otherSocialUser.id,
                },
                status: 'INVITED',
                rsvpStatus: 'UNKNOWN',
            },
        ],
    },
});

The returned value

   {
        id: '957c9707-d293-4866-979e-7e2ac58a3324',
        group: { 
                 id: 'c7df05fe-c1a0-4c9e-b26f-817b7a0bb1bf' 
        },
        user: {
           id: 'a934391d-ace0-47ff-8aa4-1ec355527652',
           displayName: 'Marc Schipperheijn',
           gender: 'M' 
       },
        status: 'INVITED' }

The rsvpStatus key is missing.

Steps to reproduce the behavior:

Expected behavior

It show a diff instead of throwing an error.

Run npx envinfo --preset jest

So, one thing I noticed is that jest-jasmnine2 on my system is 23.6.0.
However, when I force resolution to 24.8.0 I get this nasty error on all my tests:

Unfortunate that razzle depends on an old version of jest. It doesn't handle hoisted deps properly (we've tried to fix that in in jest 24). What happens if you explicitly depend on jest and jest-config? The hoisting gods might fix your issue then.

Add "jest-config": "^24.8.0", to the resolutions key solved it! Thanks!
