Hi Team,
We are currently engaged in a significant project for one of our clients. They require an End User application that would allow ticket creators to see specific information obtained via API calls.
We are currently working on it using “Build Secure End-User Apps (Beta)” guidelines. We are experiencing some issues that we would appreciate your assistance with.
When making API calls through SDK’s client.request, we receive a “403: Route not allowed” error. Interestingly, when we attempt the same requests using fetch, they work well with the exception of custom objects, which return a Cross-Origin Resource Sharing (CORS) error.
We are following the guidelines listed here: Build secure end-user apps (Beta) and here Request Method for request method. However, it appears we may be overlooking something or there could be an unknown issue at play here.
We would be grateful for your expertise and guidance on this matter. Could you please provide us with possible solutions or resources that might help us resolve this issue?
Thank you for your time and support.
