Try return [...existing, ...incoming]

[Akryum]

You should write a merge for the field which is the array: Departements: { fields: { charts: { merge... } } }

[nagaky4]

I have changed it, but nothing happens

The existing array always empty

[Akryum]

What is the graphql document?

[nagaky4]

Thanks a lot for your support, here is my graphql document.

[Akryum]

Have you configured apollo client to use 'Department' + name to identify the Departement objects? I don't see an id field on it in the query.

[nagaky4]

hi @Akryum
in my graphql document: field urn is unique so I add it in keyFields and the array can be updated now, but the pageInfo is not updated


here is the response

[Akryum]

Try a keyFields: ['department', ['urn']] on it

[nagaky4]

@Akryum thanks a lot, it works well. I'm so appreciate 🎉🎉🎉
one more thing if i use fetchPolicy : network-only

When I come back, the cache will be duplicated, please could you tell me how can I clear the cache first or another way to handle it

[Akryum]

You should probably not use network-only with fetchMore

[nagaky4]

only cache-first work, isn't it?

[nagaky4]

but for the cache-first. when i come back. i cannot get new data
