GitHub GraphQL API Filter on custom text field in Project V2 - github

Question

We are using GitHub Projects (Beta). I created a custom text field called oma-project. I want to use the API to filter on this field, e.g., oma-project: "P0001". This should return all issues with this value in the custom field.
Looking at the Projects (beta) docs, I can list the first n issues but I don't know how I can pass a filter based on the value of the custom field.
This is as far as I have gotten.
{
node(id: "nodeid") {
... on ProjectV2 {
items(first: 2) {
nodes {
fieldValues(first: 8) {
nodes {
... on ProjectV2ItemFieldTextValue {
text
field {
... on ProjectV2FieldCommon {
name
}
}
}
}
}
content {
... on Issue {
id
title
}
}
}
}
}
}
}
returns:
{
"data": {
"node": {
"items": {
"nodes": [
{
"fieldValues": {
"nodes": [
{},
{},
{},
{
"text": "Retrieve Notes via OData",
"field": {
"name": "Title"
}
},
{},
{
"text": "P9999",
"field": {
"name": "OMA Project"
}
}
]
},
"content": {
"id": "I_kwDOFT-pvM5AZNLm",
"title": "Retrieve Notes via OData"
}
},
{
"fieldValues": {
"nodes": [
{},
{},
{
"text": "Capex Approval Type",
"field": {
"name": "Title"
}
},
{},
{},
{
"text": "P0708",
"field": {
"name": "OMA Project"
}
}
]
},
"content": {
"id": "I_kwDOFT-pvM5K85HZ",
"title": "Capex Approval Type"
}
}
]
}
}
}
}

I'm having the same issue when working on a GitHub action to move a list of items from a status to another status, and it seems currently the API doesn't support ProjectV2 item filtering.
My current workaround is to query all the items from the project and then later filter out the results using jq or JavaScript
