Describe the bug

When using @graphql-toosl/mock ^8.0.0 & @graphql-tools/schema ^8.0.0. at the same time, an incompatibility appeared with @graphql-tools/merge where extractExtensionsFromSchema moved from one package to the other. The two versions of the /merge dependencies are installed and unless with yes yarn resolutions we can't fix it.

Those packages being quite coupled we often use them together.

Unless a quick patch is done we will migrate /schema to v9 to fix this on our side.

To Reproduce
Steps to reproduce the behavior:

Expected behavior

The v8.7.2 of /mock could keep targeting a v8 of /schema and a v9 of the /mock lib could be released to avoid breaking changes.

Environment:

• OS: mac
• @graphql-tools/...:
• NodeJS: 16

Sorry for inconvenience but I couldn't reproduce the issue here.

We didn't release a major version on mocks package on purpose. I don't think it is mocks package but merge package that is missing major version fixed in this PR;

[alexandrebodin]

Actually after thinking about it I even think the @graphql-tools/merge@8.3.2 should be a v9 as it removed a function without bumping a major version.

[ardatan]

But first we need to revert it as a patch release then release a major.

[alexandrebodin]

@ardatan Yes exactly adding the function to schema isn't breaking but removing it from merge would be indeed

Happy to help if I can.

[ardatan]

For the next time, I'd appreciate if you can share a reproduction on CodeSandbox or StackBlitz. Other than that, creating this issue is really helpful for me to realize my mistake :)
Thanks again.
It will be available in a few minutes on NPM.

[alexandrebodin]

Sure thing hard to reproduce easily as it kinda depends whether npm/node will want to load one version or the other anyway but noted for next time ;)

Thank you for the reactivity 🎉

[ardatan]

Could you confirm it's been fixed?

[alexandrebodin]

I can confirm this was fixed with the new patch release
