Really weird scenario where i get 404 not found error without a clear message when trying to access 2.0/sign_requests endpoint. But the same request using other applications credentials would work. There is no issue with my request as it was tested by two different environments. Here is the response i get:
"type": "error",
"code": "not_found",
"status": 404,
"message": "Not found",
"request_id": "01c6b9a375e610ba080d4a5b589c3e4f",
"context_info": {
"errors": [
"name": "Not Found",
"message": "Not Found",
"reason": "not_found"
