When trying to access one lake Microsoft fabric endpoints, this error is thrown: "Authentication Fai

[Anonymous]

I am trying to list data inside the lakehouse I have created inside Microsoft fabric by using the same scope which I use to access data inside ADLSGEN2 storage : "'https://datalake.azure.net/'", but once I try to retrieve data inside the file csv in lakehouse destination: GET https://onelake.dfs.fabric.microsoft.com/df232201-c831-424f-b32b-56157adb1202/6466dfd2-7bf6-4c9c-949..., I get an 401 Unauthorize error, with the below error message: "Authentication Failed with Audience validation failed for audience 'https://datalake.azure.net/'".

Can someone confirm if the scope used to access data inside one lake Microsoft fabric should be the same as ADLSGEN2 storage?

Yes, I was able to resolve it.

What I was trying to do is, trying to access onelake api endpoits https://learn.microsoft.com/en-us/fabric/onelake/onelake-access-api, i managed to fix it by trying to grant this scope : https://storage.azure.com/, similary to this example https://stackoverflow.com/questions/76794202/authentication-not-granted-for-service-principal-token-.... and this note in api doc "

Note

OneLake only supports tokens in the 'Storage' audience. In this example.".
