Trying to understand... Agent Script API 400 during Zendesk migration

I’m trying to figure out why the script API returns a 400 Bad Request when migrating Zendesk macros.

Background

Moving from Zendesk macros to Genesys Cloud agent scripts. Using v1 API endpoints.

Issue

Payload matches the schema, yet the system rejects the content block. Zendesk allowed plain text, but GC seems strict about formatting.

Troubleshooting

Validated JSON structure. Checked timezone settings (Europe/Paris). Still stuck on this validation error.
