描述

When running this query in the gql playground:

```gql
query GetSeriesList($host: String!, $first: Int!) {
publication(host: $host) {
seriesList(first: $first) {
edges {
node {
id
name
slug
description {
html
}
posts(first: 6) {
edges {
node {
id
title
brief
slug
publishedAt
coverImage {
url
}
author {
name
profilePicture
}
}
}
}
}
}
}
}
}

```

I get the following returned, even though there is one post in the single series in my hashnode blog:

```json
{
"data": {
"publication": {
"seriesList": {
"edges": [
{
"node": {
"id": "...",
"name": "...",
"slug": "...",
"description": {
"html": "..."
},
"posts": {
"edges": []
}
}
}
]
}
}
}
}
```

All I need to do is choose any integer that isn't `6` to get the API to return the expected post edges:

```gql
query GetSeriesList($host: String!, $first: Int!) {
publication(host: $host) {
seriesList(first: $first) {
edges {
node {
id
name
slug
description {
html
}
posts(first: 20) {
edges {
node {
id
title
brief
slug
publishedAt
coverImage {
url
}
author {
name
profilePicture
}
}
}
}
}
}
}
}
}

```

returns:

```json
{
"data": {
"publication": {
"seriesList": {
"edges": [
{
"node": {
"id": "...",
"name": "...",
"slug": "...",
"description": {
"html": "..."
},
"posts": {
"edges": [
{
"node": {
...
}
}
]
}
}
}
]
}
}
}
}
```
Hopefully this behavior is easy to map against the resolver logic.
