if you have your gateway server, just deploy and run. don't try hard, waste time.

Hi,

Is this issue has been resolved? I am facing the same issue when calling the Odata service from the local host application.

We have the SAP Gateway Hub. its working fine when calling from the Postman or any other Rest client.

Appreciate your responses.

Thanks you,

Rohit

Hi,

for those of you who still searching for a solution:
Use App Router to solve CORS
Use Proxy Server to solve CORS
(works locally and in Cloud)

Hi,

Fo testing in local only, you can use CORS pluging CORS Everywhere :: Modules pour Firefox
