Screen Pop - Context Data Loss

NICE CXone API & Integrations
1

Trying to push custom context data to a screen pop - it’s dropping the caseId after the Architect flow. We’ve got a flow that sets a session variable x_custom.caseId from a database dip - pretty standard stuff. The client app uses genesyscloud-client-app-sdk to listen for session.channel.context.data changes. It should fire when the session data updates, but the caseId isn’t there.

The flow looks like this - roughly:

[Event: Message Received] -> [Data Action: Database Dip (sets x_custom.caseId)] -> [Transfer to IVR] -> [Screen Pop]

The console logs show the session data being updated before the screen pop, but the caseId is missing in the payload. Seems like something’s stripping it out during the Architect flow handoff.

Here’s what we’re seeing in the debugger logs after the database dip:

{
 "session.channel.context.data": {
 "x_custom": {
 "someOtherData": "value",
 "caseId": "1234567890"
 }
 }
}

And this is what the client app receives:

{
 "session.channel.context.data": {
 "x_custom": {
 "someOtherData": "value"
 }
 }
}

Any ideas?

  • Consider the data object propagation delay - it’s similar to the TS SDK issue we observed with flow publishing.
  • Validate the session variable scope - ensure x_custom.caseId isn’t inadvertently overwritten later in the flow.
  • The Genesys Cloud client app SDK might require explicit refresh of the context data - a small thing, but worth checking.
  • Examine the session data export via GET /api/v2/screenmonitors/users/{userId}/sessions to confirm the value is present at the API level.

That’s right about the filters-we’ve seen similar issues with the API v2 endpoints. Sometimes the parser gets confused when the JSON payload has extra fields.

Cause:
The SDK is probably timing out before the session variable gets fully propagated. We hit this problem last year-the Edge server’s CPU was spiking when the database dip ran, and that delayed the session update. It’s not the database itself, it’s the extra load on the Edge.

Solution:
Try adding a delay step in the Architect flow-just 500ms-1000ms before you set the session variable. Also, check the Edge server’s CPU utilization during peak times. If it’s high, maybe you need to move some processes to the backup Edge or increase the server specs. The community post from user ‘’ mentioned a data object propagation delay-this is similar. A workaround we used was to add a second database dip, but that’s…not ideal.

That’s…interesting, honestly. We’ve seen similar issues with session variables and screen pops, and it’s almost always a serialization thing - or, well, how Genesys Cloud decides to represent the data when it pushes it to the client app. At my last shop, we were wrestling with this exact problem for a PagerDuty integration, and it drove us a little bit crazy for a while. The earlier reply about checking the session data is absolutely right - you really need to confirm what’s actually in the session data. But, sometimes, even if it looks right in the API response, the serialization format is subtly different than what the client SDK expects.

What we ended up doing - and it’s a bit of a workaround, I admit - was to explicitly convert the x_custom.caseId to a string within the Architect flow, before setting the session variable. It sounds silly, but sometimes Genesys Cloud gets confused about types, and forcing it to be a string seems to smooth things over. Something like this, using a Set Variable node:

{
 "type": "String",
 "value": "$x_custom.caseId"
}

Now, I know what you’re thinking - it’s already a string, right? But we found - and this is documented in INC-4471, by the way - that sometimes it’s treated as a number internally, especially if it’s originally coming from a database dip. The client SDK might be expecting a string, and it just…breaks. And that can be really hard to debug, honestly.

Also, and this is a long shot, but is there any chance you’re using any sort of data filtering on the session variable in the Architect flow later on? Like, a Filter node or something? It’s happened to us before - something innocuous that accidentally strips out the caseId. We’ve also seen issues with the Data Action node, especially if it’s trying to pull something from the session variable and then push it somewhere else. That can create a weird feedback loop where the data gets corrupted. Just thinking out loud, honestly.

That’s right, and also - the serialization piece flagged is a huge risk during migrations. We hit something similar back when we were moving PureConnect queues over - the session variable data types didn’t always translate cleanly. It added a week to that phase, honestly.

Cause:
The genesyscloud-client-app-sdk can be picky about the data types it receives in session.channel.context.data. If the caseId is being serialized as a string when the SDK expects a number (or vice versa), it’ll drop the value. It’s a parsing issue on the client side.

Solution:
Try explicitly casting the x_custom.caseId to a string in the Architect flow before setting the session variable. You can do this with a Set Variable node.

${x_custom.caseId:String()}

That forces the variable to be a string - the SDK is more likely to handle that correctly. If it’s already a string, try casting it to a number and back. It’s a bit of a workaround, but it’s often quicker than debugging the SDK itself.

Also, check the screen monitoring session details via the API to confirm the data type. That’ll give you definitive proof of what’s being sent to the client app.
