Thanks for reporting @markfarkas-camunda, do we have more information about the OpenAPI schema that the customer was using at that point? Any publicly available information? If not, do we have information about the customer so we could reach out?

[markfarkas-camunda]

Good questions! Unfortunately we do not have information about the OpenAPI schema or Postman collection the customer was using. What we have though is a partial stack trace I attached to the issue description now.
