GitHub GraphQL API Read custom field in Project V2 - graphql

Question

We are using Github Projects V2. I have created a custom field say 'MyCustomField'.
I want to read the value of custom field MyCustomField using Github GraphQL API.
I am following Gtihub GraphQL API Docs
So far I have got till reading a few predefined fields on Gtihub Issues like title, url, assignees and labels. I am using Windows PowerShell:
$project_id="MyProjectIDFetchedUsingDifferentQuery"
gh api graphql -f query='
query($project_id: ID!){
node(id: $project_id) {
... on ProjectV2 {
items(last: 20) {
nodes{
id
content{
...on Issue {
title
url
assignees(first: 10) {
nodes{
login
}
}
labels(first:5) {
edges {
node {
name
}
}
}
}
}
}
}
}
}
}' -f project_id=$project_id
I am not able to find a way to get the custom field MyCustomField.
I am expecting to write some query like below:
$project_id="MyProjectIDFetchedUsingDifferentQuery"
gh api graphql -f query='
query($project_id: ID!){
node(id: $project_id) {
... on ProjectV2 {
items(last: 20) {
nodes{
id
content{
...on Issue {
title
url
assignees(first: 10) {
nodes{
login
}
}
labels(first:5) {
edges {
node {
name
}
}
}
customFields(first:5) {
nodes {
name
}
}
}
}
}
}
}
}
}' -f project_id=$project_id

I came up with this which I think should get the custom fields on your board:
query {
node(id: "(my project id)") {
... on ProjectV2 {
items(last: 20) {
nodes {
id
content {
... on Issue {
title
url
state
assignees(first: 10) {
nodes {
login
}
}
}
}
fieldValues(first: 20) {
nodes {
... on ProjectV2ItemFieldSingleSelectValue {
field {
... on ProjectV2SingleSelectField {
name
}
}
name
id
}
... on ProjectV2ItemFieldLabelValue {
labels(first: 20) {
nodes {
id
name
}
}
}
... on ProjectV2ItemFieldTextValue {
text
id
updatedAt
creator {
url
}
}
... on ProjectV2ItemFieldMilestoneValue {
milestone {
id
}
}
... on ProjectV2ItemFieldRepositoryValue {
repository {
id
url
}
}
}
}
}
}
}
}
}

This had the basic format for querying ProjectV2 fields, and I added the
ProjectV2SingleSelectField bit to include both the field name and its value in the response.
