hi guys, how to set token and CORS(which URL to apply) to my backend, is there any video to look into?

We don’t have videos, but we have the following documentation you can consult: https://sdk.gooddata.com/gooddata-ui/docs/platform_cors.html If you are facing issues, could you please explain where you are exactly in your implementation and what errors you are seeing?

i am trying to implement my dashboard in the server , when i give yarn refresh-md i'm getting error like this..

Again, this doesn’t appear as a GoodData error. I would suggest to visit the documentation suggested from that error.

Hi, I'm getting the same error even after generating a new token ?

Have you followed outlined steps here? https://sdk.gooddata.com/gooddata-ui/docs/export_catalog.html#using-gooddatacatalog-export-with-gooddata-cloud-and-gooddatacn. You need to use API token set as variable for authentication using the tool. Make sure you specified tiger backend in

.gdcatalogrc

configuration file or starting the tool in command line with

--backend-tiger

option to reach the correct environment.
