We are currently in the hybrid operation phase of our PureConnect to Genesys Cloud CX migration. We have successfully mapped most skills and configured the hybrid trunks, but we are hitting a wall with our digital messaging integration.
Specifically, we are trying to replicate a PureConnect IVR flow that parses incoming JSON payloads from our web chat widget. In PureConnect, this was handled via the XML parser block. In Genesys Cloud, I have built an Architect flow using the ‘Parse JSON’ block. The flow receives the webhook from our middleware, but it consistently fails at the parsing stage.
The error logged in the Architect trace is: SystemError: Invalid JSON payload or schema mismatch. Expected object, got null at path $.customerData.
Here is the environment detail:
Genesys Cloud Version: 2023-11 (latest available in our region)
Architect Flow: Using the standard ‘Parse JSON’ block with a custom schema definition.
Input Payload: We are sending a standard JSON object {"customerData": {"id": "12345", "name": "Test User"}}.
I have verified the payload using Postman and it is valid. The schema in the Architect block is defined as:
The flow fails immediately upon entry to the Parse JSON block. No variables are populated. I suspect there is a difference in how Genesys Cloud handles the content-type header or the payload body compared to PureConnect’s XML parser. Has anyone encountered this during a similar migration? Is there a specific configuration in the Webhook receiver block that I am missing? Any insight into why the parser is seeing null would be appreciated. We are on a tight deadline for cutover.
The issue likely stems from how the JSON payload is being passed into the Parse JSON block. In Genesys Cloud Architect, the input must be a valid string representation of the JSON object, not a raw data structure. If your web widget is sending form-encoded data or if the payload is nested within a larger envelope, the parser will fail.
First, verify the incoming payload using the Trace tool. Ensure the content type is application/json. If the data arrives in the body attribute, you must explicitly reference it. For example, if the payload is in ${.body}, set the Parse JSON block’s input to ${.body}.
If the payload contains nested objects, ensure you are accessing the correct path. For instance, if the structure is {"data": {"user": "id"}}, you cannot simply parse the root; you must extract the data node first.
Regarding our Salesforce integration, once the JSON is successfully parsed in Architect, you can map these fields to Data Actions. I recommend creating a custom Data Action in the Genesys Cloud for Salesforce managed package to log this interaction. This ensures that the chat transcript and parsed metadata (like customer_id or intent) are written directly to the Salesforce Case or Lead record, maintaining data parity with your previous PureConnect XML logging.
Check the Architect flow error logs for specific syntax errors. Common pitfalls include unescaped quotes in string values or trailing commas in the JSON structure. If the payload is malformed at the source, the Architect flow will not recover it; you must fix the widget configuration to emit strict JSON.
Be careful with how you handle the parsed data if you are leveraging Genesys DX for downstream actions. While the Parse JSON block in Architect is sufficient for routing logic, it does not automatically enrich the session context for agent assist or auto-answer suggestions within Genesys DX. If your PureConnect flow relied on specific data points to surface KB articles or trigger auto-replies, you need to explicitly map those parsed fields to the Genesys DX integration variables.
Simply parsing the JSON in Architect leaves the data siloed within the flow execution. To ensure Genesys DX sees the context, you must use the “Set Variables” block after parsing to push the relevant keys-like customer_intent or product_type-into the session attributes that the DX connector listens to. Otherwise, the agent assist panel will remain blank because the DX engine hasn’t received the signal to query the knowledge base.
Also, watch out for data type mismatches. PureConnect’s XML parser was often more forgiving with loose types, but Genesys DX expects strict string or integer formats for its analytics and suggestion algorithms. If you pass a boolean as a string “true” instead of a JSON boolean true, the DX rules engine might fail to match the conditions for auto-answer suggestions. Validate your schema against the Genesys DX integration guide to ensure the payload structure matches their expected input format before going live. This extra step prevents silent failures where the IVR works, but the digital experience features appear broken to the agent.
