Agent Scripting API 422 Unprocessable Entity during AppFoundry Integration

Trying to make sense of why the /api/v2/agent-scripting/scripts endpoint consistently returns a 422 Unprocessable Entity error when our AppFoundry partner application attempts to programmatically update script versions for multi-org tenants using a service account with full API scope. The request payload adheres strictly to the v2 schema definition for script content updates, including valid UUID references for media assets and correct version incrementing logic, yet the validation layer rejects the submission with a generic schema mismatch error that lacks specific field details. We have verified that the OAuth token possesses the necessary agent-scripting:write permissions and that the target script belongs to the correct organization context within the multi-tenant architecture. The issue appears to be isolated to scripts containing dynamic variable placeholders that reference custom attributes defined in the tenant’s data model, suggesting a potential parsing failure within the scripting engine when processing complex variable interpolation sequences during the API-driven update cycle. This behavior disrupts our automated deployment pipeline for premium app clients who rely on version-controlled script management via our integration platform. Has anyone encountered similar validation failures when using the Agent Scripting API for bulk updates or version control operations within an AppFoundry context, particularly when dealing with scripts that incorporate advanced variable substitution logic or conditional branching based on customer data attributes?

Make sure you verify the media asset UUIDs against the active tenant context. The 422 error often stems from referencing assets in a different org, even with full scope. This creates a validation mismatch during high-throughput updates.

Check the version increment logic in your payload. It must strictly follow sequential integers. A gap in versioning triggers a schema rejection. Review the JMeter logs to confirm the payload structure matches the v2 spec exactly.
