Работает над настройкой подключаемого модуля GatsbyJS, исходящего из AWS AppSync с использованием аутентификации IAM.Я получаю сообщение об ошибке, что не могу отследить, в чем проблема.
У меня нет большого опыта работы с ссылками в Graphql, и я не могу найти хорошую документацию о том, как это сделать вэтот контекст.
Вот как выглядит файл моего плагина gatsby-node.js :
const uuidv4 = require(`uuid/v4`)
const invariant = require(`invariant`)
const fetch = require(`node-fetch`)
const { createHttpLink } = require(`apollo-link-http`)
const { buildSchema, printSchema } = require(`graphql`)
const { makeRemoteExecutableSchema, transformSchema, introspectSchema, RenameTypes } = require(`graphql-tools`)
const AUTH_TYPE = require('aws-appsync/lib/link/auth-link').AUTH_TYPE
const AWS = require('aws-sdk');
const { createAppSyncLink } = require('aws-appsync');
exports.sourceNodes = async ( { actions, createNodeId, cache, createContentDigest }, options ) => {
const { createNode } = actions
delete options.plugins
const { typeName, fieldName, refetchInterval, HOST, PATH, REGION, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY } = options
const url = HOST + PATH
// making sure things are required properly
invariant(
typeName && typeName.length > 0,
`gatsby-source-graphql requires option \`typeName\` to be specified`
)
invariant(
fieldName && fieldName.length > 0,
`gatsby-source-graphql requires option \`fieldName\` to be specified`
)
// Link to appsync
const fetcherLink = createHttpLink({
uri: url,
fetch: fetch
})
const type = AUTH_TYPE.AWS_IAM
AWS.config.update({
region: REGION,
credentials: new AWS.Credentials({
accessKeyId: AWS_ACCESS_KEY_ID,
secretAccessKey: AWS_SECRET_ACCESS_KEY
})
});
const credentials = AWS.config.credentials;
const link = createAppSyncLink({
url: url,
region: REGION,
auth: { type, credentials },
resultsFetcherLink: fetcherLink,
});
// Schema Creation
let introspectionSchema
const cacheKey = `gatsby-source-graphql-schema-${typeName}-${fieldName}`
let sdl = await cache.get(cacheKey)
console.log('sdl', sdl)
if (!sdl) {
introspectionSchema = await introspectSchema(link)
sdl = printSchema(introspectionSchema)
} else {
introspectionSchema = buildSchema(sdl)
}
await cache.set(cacheKey, sdl)
const remoteSchema = makeRemoteExecutableSchema({
schema: introspectionSchema,
link,
})
// Node creation
const nodeId = createNodeId(`gatsby-source-graphql-${typeName}`)
const node = createSchemaNode({
id: nodeId,
typeName,
fieldName,
createContentDigest,
})
createNode(node)
const resolver = (parent, args, context) => {
context.nodeModel.createPageDependency({
path: context.path,
nodeId: nodeId,
})
return {}
}
const schema = transformSchema(remoteSchema, [
new StripNonQueryTransform(),
new RenameTypes(name => `${typeName}_${name}`),
new NamespaceUnderFieldTransform({ typeName, fieldName, resolver }),
])
addThirdPartySchema({ schema })
if (process.env.NODE_ENV !== `production`) {
if (refetchInterval) {
const msRefetchInterval = refetchInterval * 1000
const refetcher = () => {
createNode(
createSchemaNode({
id: nodeId,
typeName,
fieldName,
createContentDigest,
})
)
setTimeout(refetcher, msRefetchInterval)
}
setTimeout(refetcher, msRefetchInterval)
}
}
}
function createSchemaNode({ id, typeName, fieldName, createContentDigest }) {
const nodeContent = uuidv4()
const nodeContentDigest = createContentDigest(nodeContent)
return {
id,
typeName: typeName,
fieldName: fieldName,
parent: null,
children: [],
internal: {
type: `GraphQLSource`,
contentDigest: nodeContentDigest,
ignoreType: true,
},
}
}
Это мое сообщение об ошибке:

До этого не слишком много работал со ссылками на GraphQL.Любая помощь?
