Hyperledger Composer with Custom IBM Cloudant Wallet Fails - Entity too Large - hyperledger-fabric

Question

I am creating a nodejs server where I am adding participants and creating the cards on the cloud wallet. From what I learned from playing with the composer sdk, I ended up creating a function that takes the participant details and then issues the identity and then creates a card on the cloudant. This method was working fine until today.
Suddenly I am getting 413 - Entity too large when I am trying to import the card.
Any suggestions?
const BusinessNetworkConnection = require("composer-client")
.BusinessNetworkConnection;
const NetworkCardStoreManager = require("composer-common")
.NetworkCardStoreManager;
const IdCard = require("composer-common").IdCard;
const connectionProfile = JSON.parse(
JSON.stringify(require("./connection-profile.json"))
);
const walletType = {
type: "#ampretia/composer-wallet-cloudant",
options: {
database: "composer-wallets",
apikey: "",
host: "",
iam_apikey_description: "",
iam_apikey_name: "",
iam_serviceid_crn: "",
password: "",
port: ,
url: "",
username: ""
}
};
const AdminConnection = require("composer-admin").AdminConnection;
const cardStore = NetworkCardStoreManager.getCardStore(walletType);
const bnConnection = new BusinessNetworkConnection({ cardStore });
const adminConnection = new AdminConnection({ cardStore });
const addParticipantAndIssueIdentity = userDetails => {
return new Promise(async (resolve, reject) => {
try {
await adminConnection.connect("admin#test.com");
const definition = await bnConnection.connect(
"admin#test.com"
);
const participantRegistry = await bnConnection.getParticipantRegistry(
`org.test.bna.${userDetails.role}`
);
const factory = definition.getFactory();
let participant = factory.newResource(
"org.test.bna",
`${userDetails.role}`,
`${userDetails.uid}`
);
participant.email = userDetails.email;
participant.firstName = userDetails.firstName;
participant.lastName = userDetails.lastName;
await participantRegistry.add(participant);
const returnedCard = await bnConnection.issueIdentity(
`org.test.bna.${userDetails.role}#${userDetails.uid}`,
`${userDetails.uid}`
);
const metadata = {
userName: returnedCard.userID,
version: 1,
enrollmentSecret: returnedCard.userSecret,
businessNetwork: "test"
};
const idCard = new IdCard(metadata, connectionProfile);
console.log("Importing Card 1");
await adminConnection.importCard(
`${userDetails.uid}#test`,
idCard
); <----- This call is failing
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
console.log("Request Identity");
const result = await adminConnection.requestIdentity(
`${userDetails.uid}#test`,
returnedCard.userID,
returnedCard.enrollmentSecret
);
idCard.setCredentials({
...result,
privateKey: result.key
});
console.log("Importing Card 2");
await adminConnection.importCard(
`${userDetails.uid}#test`,
idCard
);
console.log("Exporting Card");
await adminConnection.exportCard(
`${userDetails.uid}#test`
);
resolve(true);
} catch (error) {
console.log(error);
reject(error);
}
});
};
UPDATE:
I have added the error log below:

Answer 1

All flavours of Cloudant on IBM Cloud imposes a 1 meg max document size. There is no way around this, and applies to both free and paid versions. See https://console.bluemix.net/docs/services/Cloudant/api/document.html#documents
An efficient data architecture for Cloudant would typically use documents of a couple of kilobytes.
