I have the same error!

Same.

Apparently this is due to a conflict in the GraphQL dependencies between amplify-api (14.0.0) and gatsby (14.6.0).

I eventually got around this, but I'm not sure which step took care of it. I deleted node_modules and package-lock.json. I tried editing the graphql versions in package-lock.json. I also used yarn install after adding a graphql resolution to the package.json file:
"resolutions": { "graphql": "14.6.0", }

Same error

So did using Yarn work? I used NPM so maybe should try yarn, cannot see why it should change things?

[marksteven]

Yarn works much better on this for some reason.
