execute

Retrieves a single ApolloResponse from this ApolloCall.

execute calls toFlow and filters out cache or network errors to return a single success ApolloResponse.

execute throws if more than one success ApolloResponse is returned, for an example, if operation is a subscription or a @defer query. In those cases use toFlow instead.

execute may fail due to an I/O error, a cache miss or other reasons. In that case, check ApolloResponse.exception:

val response = apolloClient.execute(ProductQuery())
if (response.data != null) {
  // Handle (potentially partial) data
} else {
  // Something wrong happened
  if (it.exception != null) {
    // Handle non-GraphQL errors
  } else {
    // Handle GraphQL errors in response.errors
  }
}

The work is executed on the dispatcher configured in ApolloClient.Builder.dispatcher or a default dispatcher else. There is no need to change the coroutine context before calling execute. See ApolloClient.Builder.dispatcher for more details.
