Missing selection set for object GraphQL+Apollo error
Solution is to add fields to the query (vs. declaring the top-level object you want to fetch without specifying the fields to fetch). If you have something like:
{
popups @client {
id
dialog
}
}
you must declare some fields to fetch inside dialog
, for example id
:
{
popups @client {
id
dialog {
id
}
}
}
Answer to the actual problem seems lay in the query. Initially Apollo client was not validating types for @client
queries/mutations so your mutation could look like you wrote it in the question:
mutation AlertOpenDialog($type: String!) {
openDialog(type: $type) @client
}
the correct way of writing above is to specify (select) all the simple type (scalar) fields you wanna get in a response. So in regard to the @Vic answer the mutation should look more like:
mutation AlertOpenDialog($type: String!) {
openDialog(type: $type) @client {
dialog {
id
}
}
}
