Data Action HCL fails to parse response schema during Zendesk migration

Could someone explain why my Data Action configuration keeps failing during the validation phase? I am currently migrating our ticketing workflows from Zendesk to Genesys Cloud, and I am trying to replicate the macro-based ticket update logic we had in Zendesk. In Zendesk, updating a ticket status was a simple API call with a JSON payload. Here, I am trying to use a Data Action to push interaction data back to a custom endpoint, but the HCL definition seems to choke on the response schema.

The environment is Genesys Cloud version 2024-10. I am using the official Genesys Cloud Terraform provider version 1.105.0. The error occurs right after I run terraform apply. The flow in Architect is simple: a script block collects the data, and then the Data Action sends it. However, the provisioning fails before the flow can even be tested.

Here is the specific error I am seeing in the console:

Error: Failed to create data action: status code 400, reason: Bad Request
Details: Invalid response_schema format. Expected object type but received array.

This is confusing because my schema clearly defines the root as an object with string properties. I used to manually escape every quote in Zendesk webhooks, so I assumed the jsonencode function in Terraform would handle the formatting correctly. I have tried removing the nested objects and flattening the structure, but the error persists. The request schema seems to work fine, so the issue is strictly with how Genesys Cloud expects the response schema to be defined in the HCL.

Is there a specific syntax requirement for the response_schema that differs from standard JSON schema? Or is this a known issue with the Terraform provider when migrating complex ticket structures? I am trying to avoid writing raw JSON strings in the HCL file, as that defeats the purpose of using Terraform for infrastructure as code. Any practical advice on how to structure this correctly would be appreciated.

Check your response schema definition in the HCL file. The parser often fails if the expected JSON structure does not exactly match the actual API response, especially regarding nested objects. Since you are migrating from Zendesk, ensure the field types align. Genesys Cloud is strict about this. Try simplifying the schema to only include the critical fields needed for the next step in the flow. You can always add more fields later once the basic connection works. Also, verify that the endpoint returns a 200 OK status with the correct Content-Type: application/json header. Sometimes intermediate proxies or firewalls strip headers, causing the parser to guess the format incorrectly.

Warning: Ensure your custom endpoint does not return an empty body on success. An empty response will cause the Data Action to fail schema validation immediately.

You need to align the HCL response schema with the actual JSON structure returned by your endpoint.

  • Strip nested objects down to flat key-value pairs if possible.
  • Ensure field types match exactly (string vs integer).
  • Validate the payload against the schema before deployment.

This prevents parser errors during migration.
