Can not use useMutation in BlitzPage

[Denis Radin]

What is the problem?

I am using version 2.0.9 with AppRouter and auth. I tried to install from scratch 2 times and every time I get the same result.

I create src/pages/record/[userId].tsx where I call useMutation as following. It is expected that it just works. Instead, I am getting errors Error: No QueryClient set, use QueryClientProvider to set one

export const RecordingPage: BlitzPage<RecordingPageProps> = ({user}) => {
    const barkMutation = useMutation(registerBarkForUser);
    return <RecordingPageComponent user={user} registerBarkForUserMutation={barkMutation}/>
}

this results in

Paste all your error logs here:

Paste all relevant code snippets here:

export const RecordingPage: BlitzPage<RecordingPageProps> = ({user}) => {
    const barkMutation = useMutation(registerBarkForUser);
    return <RecordingPageComponent user={user} registerBarkForUserMutation={barkMutation}/>
}

What are detailed steps to reproduce this?

1. Create fresh project with 2.0.9
2. Add page under src/pages/record/[userId].tsx
3. Add useMutation there

you are using both app and pages directory, is the _app.tsx file wrapped with the withBlitz wrapper?
