NextJS: `HYDRATION` action doesn't receive server payload when using `redux-observable` - rxjs

Question

Packages:
redux-observable#2.0.0-rc.2
rxjs latest
universal-rxjs-ajax dev branch
next-redux-wrapper latest
next.js latest
I have a simple Page with getStaticProps:
export const getStaticProps = wrapper.getStaticProps((store) => async (ctx) => {
store.dispatch({ type: 'ADD_DATA' });
// const response = await fetch('https://rickandmortyapi.com/api');
// const data = await response.json();
// store.dispatch({ type: 'SERVER_ACTION', payload: data.characters });
return {
props: {},
};
});
Action 'ADD_DATA' triggers action 'SERVER_ACTION':
export const AddDataEpic: Epic = (action$) =>
action$.pipe(
ofType('ADD_DATA'),
mergeMap((action) =>
request({ url: 'https://rickandmortyapi.com/api' }).pipe(
map((response) => {
return {
type: 'SERVER_ACTION',
payload: response.response.characters,
};
})
)
)
);
Inside the reducer in the case 'SERVER_ACTION': clause I receive the payload:
const server = (state: State = { data: null }, action: AnyAction) => {
switch (action.type) {
case HYDRATE: {
console.log('HYDRATE >', action.payload); // logs out "HYDRATE > { server: { data: null } }"
return {
...state,
...state.server,
...action.payload.server,
};
}
case 'SERVER_ACTION': {
console.log('SERVER_ACTION >', action.payload); // logs out "SERVER_ACTION > https://rickandmortyapi.com/api/character"
return {
...state,
...state.server,
data: action.payload,
};
}
default:
return state;
}
};
But the payload isn't passed to HYDRATE action:
console.log('HYDRATE >', action.payload); // logs out "HYDRATE > { server: { data: null } }"
If I dispatch the 'SERVER_ACTION' action from inside the getStaticProps:
export const getStaticProps = wrapper.getStaticProps((store) => async (ctx) => {
// store.dispatch({ type: 'ADD_DATA' });
const response = await fetch('https://rickandmortyapi.com/api');
const data = await response.json();
store.dispatch({ type: 'SERVER_ACTION', payload: data.characters });
return {
props: {},
};
});
The HYDRATE action inside the reducer receive the payload:
HYDRATE > { server: { data: 'https://rickandmortyapi.com/api/character' } }
I don't understand what's wrong with my code.
May it be a bug in one of the libraries? Or is it a mistake in my code?
If anyone has any suggestions, PLEASE

#PYTHON DEVELOPER999 It might be due to the latest update on next-redux-wrapper, there are few migration steps =>
