I have a query like below
query {
heroes {
node {
name
}
endCursor
}
}
I am trying to understand how GraphQL can handle the error handling and return partial response. I looked at https://github.com/graphql/dataloader/issues/169 and tried to create a resolver like below;
{
Query: {
heroes: async (_) => {
const heroesData = await loadHeroesFromDataWarehouse();
return {
endCursor: heroesData.endCursor;
node: heroesData.map(h => h.name === 'hulk' ? new ApolloError('Hulk is too powerful') : h)
}
}
}
}
I was hoping it would resolve something like below;
{
"errors": [
{
"message": "Hulk is too powerful",
"path": [
"heroes", "1"
],
}
],
"data": {
"heroes": [
{
"name": "spiderman"
},
null,
{
"name": "ironman"
}
]
}
}
but it is completely failing making the heroes itself null like below;
{
"errors": [
{
"message": "Hulk is too powerful",
"path": [
"heroes"
],
}
],
"data": {
"heroes": null
}
}
How can I make resolver to return me the desired partial response?
Found the solution, basically we need a resolver to resolve the edge model itself;
{
Query: {
heroes: (_) => loadHeroesFromDataWarehouse()
},
HeroesEdge {
node: async (hero) => hero.name === 'hulk' ? new ApolloError('Hulk is too powerful') : hero
}
}
I tried following the offical Shopify Documentation for retrieving ProductMedia.
My Query looks like this:
query getProductMediaById($id: ID!) {
product(id: $id) {
id
media(first: 10) {
edges {
node {
mediaContentType
alt
...mediaFieldsByType
}
}
}
}
}
fragment mediaFieldsByType on Media {
... on ExternalVideo {
id
embeddedUrl
}
... on MediaImage {
image {
...imageAttributes
}
}
... on Model3d {
sources {
url
mimeType
format
filesize
}
}
... on Video {
sources {
url
mimeType
format
height
width
}
}
}
fragment imageAttributes on Image {
altText
url
}
The only thing where I diverged from the official documentation is to put the image attributes to another fragment for code reuse.
But when I try to execute the query I get the following response:
{
"data": {
"product": {
"__typename": "Product",
"id": "Z2lkOi8vc2hvcGlmeS9Qcm9kdWN0LzY3NjcyOTczMzEzMDU=",
"media": {
"__typename": "MediaConnection",
"edges": [
{
"__typename": "MediaEdge",
"node": {
"__typename": "MediaImage",
"mediaContentType": "IMAGE",
"alt": ""
}
}
]
}
}
},
"loading": false,
"networkStatus": 7
}
Or to put it to words my response doesn't contain any information from the mediaFieldsByType fragment.
Any Idea what I'm doing wrong?

I request for create-order then returned #PNR and now want to issue ticket. #Amadeus
As of now, this Flight Create Orders API allows you to book a flight and generate a PNR, but it does not allow for ticketing. Therefore, one of the requirements in order to use the API in production is to sign a contract with an airline consolidator to issue tickets.
Please check the requirements on the API page. If you want help to find a consolidator get in touch with us via the support channel and we can recommend you one.
I have a collection "Owners" and I want to return a list of "Owner" matching a filter (any filter), plus the count of "Pet" from the "Pets" collection for that owner, except I don't want the dead pets. (made up example)
I need the returned documents to look exactly like an "Owner" document with the addition of the "petCount" field because I'm using Java Pojos with the Mongo Java driver.
I'm using AWS DocumentDB that does not support $lookup with filters yet. If it did I would use this and I'd be done:
db.Owners.aggregate( [
{ $match: {_id: UUID("b13e733d-2686-4266-a686-d3dae6501887")} },
{ $lookup: { from: 'Pets', as: 'pets', 'let': { ownerId: '$_id' }, pipeline: [ { $match: { $expr: { $ne: ['$state', 'DEAD'] } } } ] } },
{ $addFields: { petCount: { $size: '$pets' } } },
{ $project: { pets: 0 } }
]).pretty()
But since it doesn't this is what I got so far:
db.Owners.aggregate( [
{ $match: {_id: { $in: [ UUID("cbb921f6-50f8-4b0c-833f-934998e5fbff") ] } } },
{ $lookup: { from: 'Pets', localField: '_id', foreignField: 'ownerId', as: 'pets' } },
{ $unwind: { path: '$pets', preserveNullAndEmptyArrays: true } },
{ $match: { 'pets.state': { $ne: 'DEAD' } } },
{ "$group": {
"_id": "$_id",
"doc": { "$first": "$$ROOT" },
"pets": { "$push": "$pets" }
}
},
{ $addFields: { "doc.petCount": { $size: '$pets' } } },
{ $replaceRoot: { "newRoot": "$doc" } },
{ $project: { pets: 0 } }
]).pretty()
This works perfectly, except if an Owner only has "DEAD" pets, then the owner doesn't get returned because all the "document copies" got filtered out by the $match. I'd need the parent document to be returned with petCount = 0 when ALL of them are "DEAD". I cannot figure out how to do this.
Any ideas?
These are the supported operations for DocDB 4.0 https://docs.amazonaws.cn/en_us/documentdb/latest/developerguide/mongo-apis.html
EDIT: update to use $filter as $reduce not supported by aws document DB
You can use $filter to keep only not DEAD pets in the lookup array, then count the size of the remaining array.
Here is the Mongo playground for your reference.
$reduce version
You can use $reduce in your aggregation pipeline to to a conditional sum for the state.
Here is Mongo playground for your reference.
As of January 2022, Amazon DocumentDB added support for $reduce, the solution posted above should work for you.
Reference.
With JMESPath based on the following:
If the input is
{ "app": { "usertype": "power" } }
I would like to create
{ "output": { "aslist": true } }
If the input is
{ "app": { "usertype": "simple" } }
I would like to create:
{ "output": { "aslist": false } }
I can create the output but not the conditional part. Seems like a simple if then else but I can't find any documentation on that.
Any suggestions?
You can simply use the evaluation of a condition in JMESPath as a value for your resulting JSON.
Given the query:
{output: {aslist: app.usertype == 'power'}}
On your example JSON:
{
"app": {
"usertype": "power"
}
}
This would give
{
"output": {
"aslist": true
}
}
On your example JSON:
{
"app": {
"usertype": "simple"
}
}
This would give
{
"output": {
"aslist": false
}
}
But, of course, since it is a simple evaluation of a condition based on your simplified example it would also give you a false for anything that is not of usertype being power.
